Hi, There is a new feature in Vue4 that I noticed a few days ago. When a bitmap is used for color production instead of a procedural color, there is a color blend and color mask options you can use to change the color without having to use a paint program. I tested it with the fall cherry tree here using 3 different trees on top of each other with different colors. 2 of the trees have invisible bark so it looks like only one multi-colored fall time tree entirely done in Vue.
