colormaps/foliage.png not affecting birch and spruce leaves, watercolor.png not changing water at all

the foliagecolor.png part of texture packs only affects regular oak and jungle trees. it has no effect on either spruce or birch ones, they're always default green even if you recolor your texture pack's foliage to red or blue.

same goes for watercolor, except it doesn't do anything at all. no matter what you recolor it to, water will remain blue.
