Use base16 theme as input

[mewoocat]

I was wondering if it would be feasible to implement a base16 theme input to Matugen? I understand that I could create an image palette with the given theme's colors, but being able to input a .json file and get the material colors version of the them would be very nice.

Unfortunately, all schemes are generated from a single color. Only one color is extracted from the Image and a scheme is built from it. Bigger changes are necessary for this to work.

That would require forking and modifying the material-colors library. I'm not against making small changes but I don't know about these big ones. I guess if enough people request this then I'll try to add this.

I'm not a contributor, but I wanted something like this myself because I use a program that happens to style itself with matugen. A way I can see this kind of functionality happen without making big changes to material-colors is the following approach:

• Given a base16 colorscheme and a image (or color), first determine 3 of the last 8 colors (the accent colors) are most suitable to generate the theme from. The best suited will be chosen as primary, then second best as secondary, the 3rd as ternary.
• A theme will be generated from these 3 colors. (If not possible, generating just from the primary is fine)
• The first 8 colors will be used to override the Background and Surface colors.

This approach allows augmenting a generated material theme to be augmented with the custom styling decision of a base16 theme.

What do you think @InioX? To be honest I understand if you feel like this it outside of the scope for matugen.
