I was looking around with the frogs and noticed that they spawn with the wrong color in some biomes:

Orange frogs spawn in taigas, old growth (pine and spruce) taigas, snowy taigas, groves, cold and frozen oceans (as well as their deep variants), snowy beaches, frozen rivers and windswept hills (including gravelly and forest variants), but all these biomes are cold and should spawn green frogs instead.

Green frogs spawn in the meadow biome, which is a temperate biome and should spawn orange frogs instead.

Green frogs spawn in stony peaks, which is a warm biome and should spawn white frogs instead.

Orange frogs spawn in lukewarm, deep lukewarm and warm oceans as well as lush caves, and these are hot biomes so they should spawn white frogs instead
