I built a macOS color picker that outputs Tailwind classes — 2 weeks, $19 lifetime

Good question. It came from my own workflow, but not in a "market research" way — more like accumulated annoyance.

I was using Sip [1] and Digital Color Meter, then keeping a Tailwind color chart open in a tab to map hex → class name. The picker gave me #64748b, but what I actually needed was text-slate-500. Every. Single. Time.

The realization wasn't dramatic — just noticing I was doing the same lookup hundreds of times across projects. The color value was useless without the design system token. Same pattern with SwiftUI projects: Color(red: 0.39, green: 0.45, blue: 0.55) is technically correct but Color.slate is what you actually write.

So the bet was: developers don't want a color, they want the right abstraction for their stack. The menu bar thing is just ergonomics — the real value is skipping the mental mapping step.

Re: "general utility" — I actually started more general (hex/RGB/HSL), then added formats based on what I used. Tailwind and SwiftUI came first because that's my daily work. The other formats (SCSS, Objective-C) were requests from early users who had the same friction in different stacks.
