UiColors.app, at a glance

• UiColors.app is a friendly, web-based color scale and palette generator for Tailwind CSS. You start from a single color (hex or HSL, or even a random pick), and it instantly builds a full Tailwind-style scale. It’s quick, consistent, and made for real-world UI work. (figma.pluginsage.com)

• You can preview colors in real UI situations and check contrast for accessibility right inside the app. No guessing—see how your choices behave before you commit. (uicolors.app)

What you can actually do

• Generate professional scales fast: Turn any color into a complete 50–950 Tailwind scale with a click. Perfect when you need branded hues that still feel “Tailwind-native.” (figma.pluginsage.com)

• Work with multiple color scales: Combine a few custom scales and see them together across real interface examples to judge harmony, not just hex codes. (uicolors.app)

• Preview in real components: Try your palette in 20+ UI examples (dashboards, forms, cards, etc.) so you catch issues early and ship with confidence. (uicolors.app)

• Check accessibility as you go: Built‑in contrast checks help you meet WCAG expectations while you design—no extra tools required. (uicolors.app)

• Save and organize palettes: Sign in to store your work so your team can reuse and refine it later, instead of rebuilding colors from scratch. (uicolors.app)

• API for automation: Need to standardize color generation in a pipeline? The UI Colors API returns full scales (hex + HSL), so you can script color creation and keep outputs consistent. (uicolors.app)

Pricing that’s easy to plan for

• As of September 25, 2025, UiColors.app offers a free trial and three paid tiers that unlock more examples and features: Starter ($5/mo), Growth ($10/mo), Business ($15/mo). You can also combine up to three custom scales and preview them across 20+ examples on paid plans. (uicolors.app)

Why back office teams should care

• Brand governance that sticks: Centralize approved colors, generate scales from brand hex codes, and keep them accessible to everyone. That reduces ad‑hoc color tweaks and off‑brand UI. (uicolors.app)

• Accessibility baked in: The built‑in contrast checker helps your organization meet compliance targets early, lowering risk and rework later. (uicolors.app)

• Fewer design roundtrips: Real UI previews mean fewer “looks great in theory, fails in UI” moments. You spot issues before handoff and cut review cycles. (uicolors.app)

• Repeatable, auditable outputs: With the API, you can standardize palette generation in build scripts or design-token pipelines, so every app uses the same source of truth. Consistency = less maintenance overhead. (uicolors.app)

• Smooth onboarding: Saved palettes make it easy for new teammates and vendors to apply the right colors from day one, reducing ramp-up time. (uicolors.app)

Where it fits in your stack

• Tailwind-first workflows: UiColors outputs Tailwind-ready values (including OKLCH for v4), so your teams can copy and drop color data straight into projects without manual translation. (uicolors.app)

• Design tools and plugins: There’s a Figma plugin based on UiColors for generating scales inside design files—handy for designers who want parity with the dev palette. (figma.pluginsage.com)

• Pipelines and tokens: Use the API to generate scales programmatically and sync them to your design tokens or CI/CD steps. It’s a neat way to keep brand colors in lockstep across apps and docs. (uicolors.app)

Quick reality check (so you plan accurately)

• Chrome extension: UiColors includes built‑in contrast checking in the web app; we couldn’t verify an official UiColors Chrome extension. Plan on using the in‑app checker (or a third‑party extension if you prefer browser‑level testing). Also note the API terms restrict using the API to create competing plugins/extensions, which hints there isn’t an official one. (uicolors.app)

Bottom line

• UiColors.app helps non-designers and designers alike create consistent, accessible, Tailwind‑ready palettes in minutes. For back office teams, that means clearer governance, fewer support loops, and faster delivery of internal tools and customer‑facing UI—all while staying on brand and on spec. (uicolors.app)
