Color Review (color.review) is a beautifully made free color contrast tool by Anton Lovchikov focused on making accessible color decisions easier through clear visual feedback — adjust two colors with sliders, see real-time WCAG contrast ratio + AA/AAA pass/fail + live preview of how the text actually renders on the background at multiple sizes. Tagline 'Colors for everyone. Building a tool for a better web.' Uses LCH (Lightness-Chroma-Hue) color space rather than HSL for perceptually-uniform color manipulation — adjusting lightness in LCH produces visually consistent changes while HSL's lightness slider has inconsistent perceptual effects across different hues. Shareable URLs for sending color pairs to teammates, free + browser-based + no signup. Distinguished from WebAIM Color Contrast Checker (the de-facto free standard — simple, functional, perfect for quick pair-checking) by design craft + LCH perceptual color science + live text preview, distinguished from Contrast by Sam Soffes (Mac menu-bar app faster for quick checks via system access) by deeper in-tool color manipulation during contrast checking, distinguished from Stark Figma plugin (Figma-integrated accessibility tooling) by general-web standalone + LCH color science focus, distinguished from Leonardo by Adobe (contrast-target-driven palette generation across ramps) by individual pair-checking vs palette generation scope, distinguished from Chrome DevTools contrast checker by deeper tooling + LCH controls. Free indie tool with no monetization; Anton Lovchikov also runs LCH Picker (lch.oklch.com) and other perceptually-uniform color-science tools. Best for designers crafting accessible color palettes who want predictable perceptual changes during contrast iteration via LCH sliders, designers tweaking text + background combinations with live preview of actual text rendering at multiple sizes (not just abstract contrast ratios), designers + developers learning LCH color science vs HSL inconsistencies, and teams sharing color decisions with specific pairs verified for accessibility via shareable URLs through Slack + Linear + Notion. Skip if you need menu-bar Mac access for fastest quick checks (Contrast by Sam Soffes is faster system-level access), Figma-integrated contrast checking inside the design tool (Stark is purpose-built for that), simple no-frills WebAIM-style pair-checking without LCH controls, or full design system color ramp generation (Leonardo by Adobe + ColorBox handle systematic scope). Excellent thoughtful indie tool in 2026 — exemplifies the kind of design-craft + perceptual-color-science tools that elevate the broader accessibility-color-tool ecosystem alongside Contrast + WebAIM + Stark + Leonardo + Color Safe.

How indie founders use Color Review
Accessibility-first color design
Designers crafting accessible color palettes with LCH sliders that give predictable perceptual changes during contrast iteration.
Color craft with live preview
Designers tweaking text + background combinations with live preview of how the text actually renders — not just contrast ratios in isolation.
Perceptual color exploration
Designers + developers learning LCH color science by working with sliders that produce visually-consistent changes vs HSL's inconsistencies.
Share color decisions with team
Shareable URLs let designers send specific color pairs (and the contrast verification) to teammates + clients via Slack + Linear + Notion.
Color Review (color.review) is a beautifully made color contrast tool by Anton Lovchikov, focused on making accessible color decisions easier through clear visual feedback — adjust two colors with sliders, see the contrast ratio + WCAG pass/fail + visual preview of how the text actually looks on the background. Tagline: 'Colors for everyone. Building a tool for a better web.' The design itself is exemplary — clean typography, thoughtful interaction, exactly the kind of tool that feels like it was built by a designer who cares deeply about the problem. What you get: dual-color picker (foreground + background) with sliders for hue + saturation + lightness, real-time contrast ratio calculation, WCAG AA + AAA pass/fail indicators for normal + large text, live preview of actual text rendered in the chosen colors at multiple sizes, shareable URLs so you can send a color pair to a teammate, and an underlying focus on color science (LCH color space rather than HSL for perceptually-uniform color manipulation). Free, browser-based, no signup. Where Color Review fits: among contrast-checking tools, Color Review's positioning is design-craft + perceptual color science. WebAIM is the de-facto free standard (simple, functional, gets the job done). Contrast by Sam Soffes is the Mac menu-bar power tool. Stark is Figma-integrated. Leonardo is target-driven palette generation. Color Review is the 'thoughtfully-designed contrast tool with perceptual color controls' option — uses LCH (Lightness-Chroma-Hue) sliders which produce more intuitive color changes than HSL or RGB for accessibility work. Where it's not for you: if you need menu-bar accessibility on Mac, Contrast is faster (system-level access). If you need Figma-integrated contrast checking, Stark is purpose-built. If you don't care about LCH vs HSL color manipulation and you just want quick pair-checking, WebAIM is fine. Color Review's appeal is design craft + perceptual color science — if those don't matter to you, simpler tools work. Pricing: free. Indie tool, no monetization that I'm aware of. Honest take: Color Review is the kind of indie design tool I want more of — built by someone who clearly cares, thoughtful at every level, free, no enshittification. Anton Lovchikov also runs the LCH Picker (lch.oklch.com) and has been quietly improving the color tool ecosystem with perceptually-uniform color tools that move beyond HSL. Bookmark Color Review for occasional contrast work, especially when you want to also tweak colors during the contrast-checking process rather than just check existing pairs.

Frequently asked questions
Is Color Review free?
Yes — completely free browser-based tool with no signup required. Indie tool by Anton Lovchikov.
Why LCH color space instead of HSL?
LCH (Lightness-Chroma-Hue) is perceptually uniform — adjusting lightness in LCH produces visually consistent changes, while HSL's lightness slider has inconsistent perceptual effects across different hues. For accessibility work where you're trying to hit specific contrast targets, LCH gives more predictable + intuitive color adjustments than HSL or RGB.
Color Review vs Contrast (Mac app)?
Contrast (Sam Soffes's Mac menu-bar app) is faster for quick checks via system menu bar — fewer clicks. Color Review is more in-depth — live preview, color tweaking with LCH sliders, perceptual color science. Use Contrast for quick checks, Color Review when you're designing colors and want to tweak during contrast checking.
Color Review vs WebAIM?
WebAIM is the de-facto free standard contrast checker — simple, functional, perfect for quick pair-checking. Color Review is more design-crafted with LCH sliders + live text preview + perceptual color science. Use WebAIM for quick checks, Color Review for designed accessibility work.
Who built Color Review?
Anton Lovchikov, an indie designer + developer who quietly contributes excellent color tools to the design community. Also runs LCH Picker (lch.oklch.com) and other color-science-driven tools that move beyond HSL toward perceptually-uniform color manipulation.
