Colir

Colir is a web-based gradient design tool that lets designers create sophisticated, non-default gradients using curve-based controls on the X and Y axes rather than traditional linear or radial gradient methods. It is GPU-accelerated via WebGL, enabling smooth editing at 2K-plus resolution with no render wait, and offers 12 blend modes including Multiply, Screen, and Overlay. Colir includes visual effects such as noise, glitter, feathering, and distortion, 9 built-in color palettes, real-time preview and editing, and high-resolution export from 1x to 4x scale in PNG or WebP formats. The tool is actively maintained with upcoming features including animated gradients, Figma integration, and a templates library. Pricing is freemium: a Free tier allows 5 daily exports for personal use, a PRO Monthly plan is $7/month for unlimited exports and commercial use, and a Perpetual License is available for a one-time $49 payment with the same PRO features and no renewals, backed by a 30-day money-back guarantee.
