About the Modern Color Picker & OKLCH Palette Studio
Building accessible, systematic color scales in legacy RGB or HSL often leads to unpredictable perceptual shifts, such as yellow appearing much brighter than blue at the same lightness value. Color Studio utilizes the modern OKLCH color space, an advanced cylindrical model aligned with human vision, ensuring that lightness and chroma scale consistently across your UI theme tokens.
🔬 OKLCH Perceptual Accuracy
Eliminate muddy color interpolation. OKLCH guarantees linear perceptual lightness (L), colorfulness/chroma (C), and hue (H) without the hue distortions typical of legacy sRGB tinting.
♿ WCAG 2.1 Contrast Testing
Real-time relative luminance auditing against light and dark text surfaces, confirming compliance with WCAG 2.1 AA (4.5:1 ratio) and AAA (7:1 ratio) standards for inclusive interfaces.
📱 Multi-Platform Token Export
One-click export of systematic 50 to 950 shade progressions directly into CSS Custom Properties, Tailwind CSS configuration objects, Flutter Color classes, Swift SwiftUI Color tokens, and Jetpack Compose Color definitions.
Frequently Asked Questions
Why choose OKLCH over traditional HEX or HSL?
In HSL, colors with 50% lightness have wildly different perceived brightness (for example, pure yellow appears blindingly bright while pure blue appears dark). OKLCH fixes this perceptual flaw: two colors with identical L values have identical perceived lightness, making it the superior mathematical choice for automated UI theme generation.
What contrast ratio is required for WCAG 2.1 AA compliance?
WCAG 2.1 Level AA requires a contrast ratio of at least 4.5:1 for normal body text (below 18pt or 14pt bold) and at least 3:1 for large text and essential user interface components such as form borders and interactive icons.
Can I extract color palettes from an uploaded image?
Yes. You can upload any JPEG, PNG, or WebP screenshot. The tool extracts dominant and accent colors locally on your device using HTML5 canvas pixel analysis without uploading the image to any external server.
