At first sight, Alces alces seems nondescript in colouration (https://www.inaturalist.org/observations/19029155 and https://www.inaturalist.org/observations/4336204).
Valerius Geist, on pages 229-232 in Grzimek's Animal Life Encyclopedia (https://en.wikipedia.org/wiki/Grzimek%27s_Animal_Life_Encyclopedia), exaggerates somewhat when he states:
"European moose are dark brown with white legs, and American moose are black with a light saddle patch on the back, light-brown legs, and facial markings that vary between the sexes. In the female the face and nose are red-brown, while the bull has a black nose".
The following verify that the face tends to be paler than the neck and torso, in females of A. alces in North America (https://www.inaturalist.org/observations/178372818 and https://www.dreamstime.com/bull-moose-water-image259482733 and https://www.inaturalist.org/observations/8288949) and to some degree also in Europe (https://www.inaturalist.org/observations/175016790 and https://www.inaturalist.org/observations/174910182).
However, the difference in tone between the face and the rest of the figure is noticeable only in A. a. americana (see details in comment below, titled FACIAL FLAG IN ALCES ALCES AMERICANA).
Sexual differences in the colouration of the pelage of A. alces, beyond the face, are remarkably limited (https://www.inaturalist.org/observations/42138516 and https://www.youtube.com/watch?v=bujmogxgtp4 and https://www.youtube.com/watch?v=tsZUaGIt-r8 and https://www.google.com.au/search?q=Moose+mating&sca_esv=567242663&sxsrf=AM9HkKnsy5ar25NAM_QxNryBAc4ELWtrPA%3A1695294882706&source=hp&ei=oiUMZd3UJtixoATxmJzQAg&iflsig=AO6bgOgAAAAAZQwzssn9atv3I45ihgDieVv4Z3QxBVPr&ved=0ahUKEwjdrZPKybuBAxXYGIgKHXEMByoQ4dUDCAs&uact=5&oq=Moose+mating&gs_lp=Egdnd3Mtd2l6IgxNb29zZSBtYXRpbmcyBRAuGIAEMgUQABiABDIFEAAYgAQyBRAAGIAEMgUQABiABDIFEAAYgAQyBRAAGIAEMgUQABiABDIFEAAYgARImklQzg5Y-j5wAXgAkAEAmAGuA6AB_BiqAQkwLjEuOS4xLjG4AQPIAQD4AQGoAgrCAgcQIxjqAhgnwgIEECMYJ8ICCxAAGIAEGLEDGIMBwgIREC4YgAQYsQMYgwEYxwEY0QPCAgsQLhiDARixAxiABMICCxAAGIoFGLEDGIMBwgIHECMYigUYJ8ICCBAuGIoFGJECwgIIEAAYgAQYsQPCAggQABiKBRiRAsICCxAuGIoFGLEDGJECwgILEC4YgAQYxwEYrwE&sclient=gws-wiz#fpstate=ive&vld=cid:25246631,vid:YvNAJLygu9w,st:0). Even in the case of the face, males retain the female colouration as long as the antlers are still in velvet (https://www.daveshowalter.com/photo/bull-moose-portrait/).
Infants, although noticeably paler than adults, have colouration so plain that it, too, is nondescript (https://www.inaturalist.org/observations/4097272).
Seasonal changes in colouration are limited. There is a single annual molt (https://www.inaturalist.org/observations/108839229 and https://www.inaturalist.org/observations/125310240 and https://www.inaturalist.org/observations/22740621 and https://www.inaturalist.org/observations/20313689) in spring/early summer. The pelage, after being worn and weathered for a year, fades somewhat (https://www.inaturalist.org/observations/8449050).
However, the pelage remains dark enough in winter to be conspicuous against snowy backgrounds, even at distance (https://www.inaturalist.org/observations/148799385 and https://www.inaturalist.org/observations/135953868).
Despite the initial nondescript impression, my close scrutiny has revealed several noteworthy patterns of colouration, which deserve names, in A alces.
For example, the following shows a fibular flag, anterior auricular semet, and buccal semet in an adolescent female individual in the spring season, in Alces alces gigas: https://www.inaturalist.org/observations/163382249.
Although these features are subtle, individually variable, and perhaps seasonally variable, most of them occur in most of the nine subspecies.
CORNUAL FLAG
The antlers of A. alces, borne seasonally by males, tend to be conspicuously pale on the upper (dorsal) surface, in the subspecies with the largest antlers (https://unsplash.com/photos/Du8sGaNHVMc).
The cornual flag is derived essentially from the natural paleness of dry bone (https://www.inaturalist.org/observations/127384241).
However, in A. a. gigas and presumably A. a. buturlini,
This makes the antlers conspicuous, even at distance (https://www.inaturalist.org/observations/4612251).

The fibular flag is best-developed in the nominate subspecies, A. a. alces, of Europe and western Russia, in which it tends to extend to the inner surface of the buttock (https://www.inaturalist.org/observations/149814632) and/or the hock.
The role of sheen deserves investigation.
The following shows the extreme development of the pale pelage in A. alces, in which it encompasses most of the hindleg (https://www.inaturalist.org/observations/112176729).
PEDAL FLAG
A case can be made that A. alces possesses a pedal flag, in some individuals. This applies particularly to the nominate A. a. alces (https://www.inaturalist.org/observations/142224245 and https://www.inaturalist.org/observations/142020077).
This pedal flag consists of conspicuous pale on the hocks and carpals (particularly on the posterior surface of the carpals), extending to varying extent down the lower limbs towards the hooves, and connected to the fibular flag where the latter is present (https://www.alamy.com/stock-photo-bull-moose-crossing-the-road-denali-national-park-alaska-usa-29001311.html?imageid=984BF44C-2D52-4F90-BF1B-9372BC0185A4&p=29229&pn=1&searchId=acbc6be48e9684687a1dabcb59018a60&searchtype=0).
The fetlocks and pasterns themselves are not whitish (https://www.gettyimages.com.au/detail/news-photo/december-2022-sweden-%C3%B6ster-malma-a-bull-moose-stands-in-the-news-photo/1246124150?adppopup=true and https://www.gettyimages.com.au/detail/news-photo/december-2022-sweden-%C3%B6ster-malma-a-bull-moose-stands-in-the-news-photo/1246124213?adppopup=true and https://www.shutterstock.com/image-photo/front-split-hoofs-moose-standing-on-727556374 and https://www.inaturalist.org/observations/134620144 and https://www.inaturalist.org/observations/35655176 and https://www.inaturalist.org/observations/55865091), except in some individuals of the nominate A. a. alces (https://www.mostphotos.com/en-us/25919107/moose-or-european-elk-alces-alces-hooves).
A factor undermining the validity of a pedal flag in A. alces is that, for much of the year, the pale on the legs is inconspicuous against a background of snow (https://www.inaturalist.org/observations/42170238 and https://www.inaturalist.org/observations/143176855).

https://www.inaturalist.org/observations/33064841
https://www.dreamstime.com/large-brown-black-bull-moose-standing-park-image193883277
https://www.dreamstime.com/stock-photo-moose-bull-elk-standing-road-image66248282
To the degree that the pedal flag is valid in A. alces, it is linked to, and subsidiary to, the fibular flag (https://www.inaturalist.org/observations/142257592). In A. a. alces, the joint pattern can perhaps be called a pedofibular flag.
ANTERIOR AURICULAR SEMET
Please see https://www.inaturalist.org/journal/milewski/55694-ten-best-illustrations-of-auricular-semets-in-deer#
One of the most consistent patterns of colouration in A. alces is a small-scale dark/pale contrast on the anterior base of the ear pinna (https://www.dreamstime.com/stock-photo-moose-north-america-elk-europe-alces-alces-largest-extant-species-deer-family-moose-distinguished-image50713041).
The location of this pattern is such that it accentuates the movements of the ears, in vigilance and emotional expression. Such accentuation is hypothetically adaptive in social (intraspecific) interactions, and may additionally function in anti-predator, defensive displays.
Several other genera of cervids possess auricular semets. However, that of A. alces is restricted to the anterior surface, and has its own particular configuration.
The following show the anterior auricular semet in various subspecies of A. alces:

https://www.inaturalist.org/observations/166029819
A. a. shirasi:
https://www.inaturalist.org/observations/174251418
In Alces alces, unlike another large cervid partly sympatric with it, the auricular semet does not disappear in mature males (see https://colombia.inaturalist.org/journal/milewski/69281-intriguing-new-sexual-dimorphism-in-the-wapiti).
The following show that the anterior auricular semet, although absent in newborns, develops before the infantile colouration is lost, and before the muzzle develops:
https://www.inaturalist.org/observations/133091834
https://www.dreamstime.com/stock-photo-small-moose-few-days-standing-woods-next-to-pine-tree-image53403214.
BUCCAL SEMET
The peculiar muzzle of A. alces is so distracting that the colouration around the mouth may go unnoticed. Furthermore, this colouration is subtle and individually variable.
However, there tends to be a pattern in which the broadly dark lower lip is offset by pale ventral to the gape. The clearest illustration is https://www.inaturalist.org/observations/65908659.
The following are additional illustrations:
https://www.inaturalist.org/observations/152098783 and https://www.inaturalist.org/observations/148835598 and https://www.inaturalist.org/observations/13505171 and https://www.dreamstime.com/stock-photo-moose-eating-green-grass-near-water-grand-tetons-national-park-image50021650 and scroll to second photo in https://journals.openedition.org/paleo/5126 and https://www.inaturalist.org/observations/157638267 and https://www.inaturalist.org/observations/120152994 and https://www.inaturalist.org/observations/37290353 and https://www.inaturalist.org/observations/65278592 and https://www.inaturalist.org/observations/56223948 and https://www.inaturalist.org/observations/162881182.
This pattern of colouration hypothetically accentuates the chewing movements (https://www.inaturalist.org/observations/88438853). This hypothetically aids vigilance during rumination, when two or more adult/adolescent individuals rest within sight of each other (https://www.dreamstime.com/stock-photos-moose-image20463023).
Buccal semet in Alces alces buturlini:
https://www.alamy.com/female-moose-alces-alces-in-profile-kronotsky-zapovednik-nature-reserve-kamchatka-peninsula-russian-far-east-december-image263189582.html?imageid=8337E994-E81B-42C7-9D06-32050AEFBBE0&p=216449&pn=1&searchId=693543c6c0b82d61e979d27d23f7d17f&searchtype=0

https://www.inaturalist.org/observations/2646616
https://www.inaturalist.org/observations/13172080
Variation in this feature deserves further investigation. The pattern seems clearest in spring, when the worn, weathered pelage has faded but the dark on the lower lip has not faded (https://www.inaturalist.org/observations/5155147). The following shows the minimal expression of the buccal semet (https://www.inaturalist.org/observations/114831099), but it is unclear whether this is because of the summer season or individual variation.
Of all the features described here, the buccal semet is the most precocial, in the sense that the lower lip is dark even in infants (https://www.inaturalist.org/observations/29864809 and https://www.123rf.com/photo_188787653_portrait-of-a-walking-cow-moose-and-her-calf-alces-alces.html and https://www.inaturalist.org/observations/7440096).

The withers tend to be pale, offset by the darkness of the short mane (https://www.alamy.com/cow-moose-feeding-48-image3090722.html?imageid=C50F6C04-892C-4860-A68F-4E654C45722E&p=166893&pn=1&searchId=f41a66b0ac6853a16f070809256f1de5&searchtype=0 and https://www.dreamstime.com/royalty-free-stock-photos-large-moose-field-rocky-mountain-national-park-image40381468 and https://www.dreamstime.com/stock-photo-moose-bull-alaska-usa-standing-fall-colour-meadow-lone-image78127514 and https://www.inaturalist.org/observations/214913).
However, this pattern is never graphic enough, in any subspecies/individual, to warrant a name. Furthermore, it is disrupted by the weathering, fading, and molt of the pelage, more than any other aspect of colouration (https://www.inaturalist.org/observations/76352986).
It is perhaps surprising that the dewlap of Alces alces lacks conspicuous colouration (https://www.inaturalist.org/observations/35801756).

Weren't the American subspecies recognised as a separate species a while back?
@paradoxornithidae
Valerius Geist regarded Alces as consisting of two 'types', one of which occurs in North America plus eastern Asia - intriguingly including the small form, cameloides, of Manchuria (https://en.wikipedia.org/wiki/Manchuria) and Ussuri (https://en.wikipedia.org/wiki/Ussuri).

FACIAL FLAG IN ALCES ALCES AMERICANA
In Alces alces americana of eastern North America, the face tends to be so much paler than the neck and body that this may be an adaptively conspicuous feature.
The process producing this pattern is that the face remains the same colour from birth to adulthood (https://www.inaturalist.org/observations/17977223).

In adult males in hard antler, the rostrum turns dark:

The paleness of the face in A. a. americana does not detract from the validity of the anterior auricular flag:

The facial flag does not categorically distinguish subspecies americana, because even in the far west of Russia some individuals (of the nominate subspecies, alces) show similar colouration (https://www.inaturalist.org/observations/173995526).

DETAILS OF SEXUAL DIMORPHISM IN COLOURATION OF PELAGE
The following individual of Alces alces shirasi is an exception to the rule that the pelage of the rostrum of the face turns dark once the antlers turn hard, each year:

The following is a converse exception, in which the rostrum is already dark, despite the antlers still being in velvet:

The following shows that the rostrum remains dark after the antlers are shed, in winter:

The following shows an optical effect that the human optical system would normally edit out, viz. the reflection of the blue of the sky on the whitish surface of the antler:
