Hello there, my fellow devs!

I made a swatch tool for Unity to help me create changeable themes for my game (more of a platform, really).

I often got stuck on what color a sprite should have for it to look good (it didn't look good). Now I don't have that problem.
I use my swatches and get colors from an image that someone who knows their colors has created.

I'm a programmer by heart, not an artist, but when I limit myself, I find the art creation process much easier, for example, now I'm making pawns in resolution 8x8, in grayscale: tone white and light gray. And I'm proud of my work (almost as much as of this tool).

My recommendation: LIMIT YOURSELF AND YOU'LL BE MORE CREATIVE, and try out my tool ; )
