Blendoodle 154 (Cycles, Geometry Nodes)
This one was sparked by @Debuk 's post here: World color and shadows - #44 by Debuk
While I had come up with a seperate similar one, it was Debuk’s second RGB node that sparked the idea, what if i have one colour background, but a different colour ambient light?
The trees are from @Renzatic 's GeoTree .55: GeoTree: Procedural Trees in Geometry Nodes - #1147 by Renzatic
