Maybe a mod could help me make a poll in this thread and we could hold a vote for what size pack we want? It seems like the consensus is that everyone likes the purple, orange, and pink idea. It seems still split between white or black legends, with a slight lean towards black.
I think ideally I want to make a mod pack sort of like my RGBYK but with a bit less compatibility to reduce costs. I think a light weight pack might appeal more. Also I do want to include an enter, arrow keys, and an escape key.
Edit: also just realized I might already have something like the color palette I posted. Not that it matters, but I was just browsing my own photos and saw that it was similar.
