For some reason when I use this it makes the azalea leaves turn colors?

The leaves in my hand are the correct color, the ones on the ground is what color I turns when I put it down. I've tested it and its only Better Leaves causing the color change and it does it to vanilla and every resource pack I tried.

(screenshots here)

Probably related to OptiFine, I'll fix it in the next release.
It's looks kinda cool however, doesn't it? :)

apparently this is happening to me as well but im not using optifine i use sodium.. this is the texture pack im trying to use with it
