An excerpt from the article 20 facts about Blue-Tongued Lizard

Central blue-tongued lizards are brown to gray with stripes, some, like the Western blue-tongued lizards, are pale with brown stripes, while others, like the Adelaide pygmy blue-tongued lizards, are rusty to gray with no stripes at all.

Color may also depend on habitat type - better camouflaged lizards tend to live and thrive longer.
