In ice/snow biomes some blue Flighters will have lighter colors such as pale blue or even pure White who can bend light, a rare power of Blue Flighters, to blend into the snow.

If Blue Flighter live in the open ocean or the deep ocean might have darker blue coloring and even sometimes a pale silver to look like a 'phantom whale' and in some cases have a lighter underbelly and a dark back

If several generations of Flighters live in coastal waters or in coral reefs their color might shift to match coral, with some even being mistaken for other color groups like red or purple, and they might get even more exotic colors with some having pink or orange colors.

If living is kelp forests they may have stripes of green or be full green

Living by the shore or in murky water like a swamp might give them brown, grey or even black colors
