Camouflage colouration commonly uses muted greens, browns and greys that blend with a specific background, often combined with patterns such as countershading, disruptive colouration or seasonal colour change — the effectiveness of any camouflage colour depends heavily on the specific habitat and the viewer's vision.

This gecko's skin doesn't just match a generic 'bark colour' — its blotched pattern and grey-brown tones closely track the specific lichen and bark texture of the trees it lives on.
This is a genuinely difficult photograph to extract colour from by design — the gecko's camouflage means its body and the bark behind it share almost the same palette, which is the point being illustrated."Uroplatus henkeli, Tanafisaka, Sainte-Marie, Analanjirofo region, Madagascar" by Anai171, CC BY 4.0, via Wikimedia CommonsDisruptive colouration — bold contrasting patterns such as stripes or blotches — works by breaking up an animal's outline against a visually complex background, rather than by matching a single background colour.

Countershading, a darker back and paler belly, is one of the most widespread camouflage patterns across land and marine animals, counteracting the animal's own shadow to flatten its apparent three-dimensional shape under typical overhead lighting.

Many reptiles and amphibians, such as certain frogs and chameleons, use mottled green and brown patterning to blend with leaf litter, bark or foliage, and some species can actively adjust their colour in response to their surroundings.

Seasonal camouflage colour change, such as a coat turning white for winter snow cover, is well documented in species including the Arctic fox and ptarmigan, though the timing depends on day length rather than snow itself, which can be a mismatch risk as climate patterns shift.
