Designer color math toolkit

Plugins for design tools that quantify color relationships and accessibility gaps. Gives exact WCAG compliance metrics during design.

Why now

Design systems demand precise color math, but most tools still rely on eyeballing contrast.

Who for
Product and system designers
Business model
SaaS subscriptions
Effort
A few weeks

Designers manually check contrast ratios and tweak HSL values. The math exists but isn't integrated into creative workflows.

Build Figma/Sketch plugins that show real-time color metrics: delta-E, perceptual brightness, and accessibility scores as you adjust palettes.

Sell to design teams managing systems at $5-10/seat/month. Offer free tier for individual designers.

Start with basic contrast checking, then add advanced color space visualizations.

Risk: Niche audience may not justify standalone product - might need to bundle.
