Hello there, this is probably a bit daft, but I just thought about this while working in Pencil2D.
I think it could be quite useful to allow hotkeys to switch between a few of the predefined palette colours on-the-fly. I’m using Pencil2D mainly for the pre-inking stage of animation, so being able to quickly switch between a light shade for loose lines, a slightly bolder colour to refine and a final darker colour for the final details would be super useful.
I’m not sure if many others are using Pencil2D in conjunction with other tools in a similar fashion, but if they are, I’d imagine they’d also find this really useful.
Otherwise; just an idea I’d put out there. Thanks for reading
