Here are four recolours of the Birch Sapling tree.
They have four states: spring and summer are the same, fall is separate, and have two states for winter: simply bare, and snow-covered.
The appropriate colours also show up from 'hood view. (At least I tried - do tell me if you think they don't match enough.)
My thanks to
Bienchen for her recolouring template. Files are
Compressorized - thank you jfade.
They were made for Seasons, but may work without it. Please tell us if you've tried.
