KColor

What it does

kcolor.co is a smart, fast color palette generator for designers and devs. Generate and tweak your palette just by describing what you want—no color theory required. Say ‘make it bolder’ or ‘swap the last color for a pastel green’ and KColor does the rest.

The project had traction (1.4k GitHub stars, 95 forks, ~20K visits/month), but was eventually sold due to video licensing hurdles. The new owner stopped maintaining it, and the repo went abandoned. Over the next 9 months, I sent 15 emails to try to save it : no replies. Feature requests & issues were ignored. The community was left with a "broken" tool let's say. I couldn't just let it die So I built the new version from scratch with the same open-source spirit, but a better…
