The Best Free Color Palette and Gradient Tools in 2026

Curated by Musharof Chowdhury · Last reviewed October 16, 2026 · How we pick

Choosing colours involves three different jobs: finding a palette, turning it into a usable scale of shades, and checking that text stays readable. Few tools do all three well, so this shortlist covers the best free option for each.

A common workflow: generate or browse palettes in Coolors or Color Hunt, build tints and shades with UI Colors, preview the result on a real layout in Realtime Colors, then check contrast with WebAIM.

Frequently asked questions

What is the best free color palette generator?

Coolors is the fastest way to generate palettes, Color Hunt is best for browsing ready-made ones, and Adobe Color is best if you want palettes based on colour-theory harmonies. All three are free.

How do I check if my colours are accessible?

Use the WebAIM Contrast Checker. Normal text needs a contrast ratio of at least 4.5:1 against its background to meet WCAG AA, and large text needs at least 3:1.

How do I create a Tailwind CSS colour palette?

Enter your brand colour in UI Colors to generate a 50–950 shade scale, then paste the exported values into the colors section of your Tailwind configuration.

Where can I find free CSS gradients?

Grabient and uiGradients have galleries of ready-made gradients with copyable CSS, and CSS Gradient lets you build your own visually.
