Why choose Kasuality?
Kasuality is not a simple random generator. It's a tool designed for Designers, Developers, and Creatives who need mathematical coherence and future accessibility. Unlike standard generators, we use the HSL color space for harmonies, but integrate APCA vision science and AI Color Analysis to bring you professional results.
Multichromatic Manual Editor
Enter up to 5 colors separated by a comma to instantly create your custom palette. If you enter fewer, Kasuality will automatically complete the harmony for you.
HSL Color Geometry and Golden Ratio
Beyond classic harmonies (Monochromatic, Analogous, Complementary), generate complex schemas like Split-Complementary, Tetradic, and the Golden Ratio (φ). Leverage the HSL space for perfect coherence.
WCAG 2.1 and APCA (WCAG 3)
Don't limit yourself to the past. Kasuality verifies standard WCAG 2.1 (AA/AAA) contrast, but also introduces the new APCA (Lc) perceptual algorithm, simulating real human vision for uncompromising accessibility.
HSL Control and Smart Lock
Like a color? Lock it with the padlock and continue generating harmonious variants. Kasuality alerts you when manual changes break mathematical harmony, ensuring transparency and control over HSL values at all times.
AI Color Analysis and Image Picker
Not just color extraction: our hybrid AI analyzes skin tone and vein undertones to identify your Seasonal Color Palette (out of 16 variants, from Deep Winter to Soft Summer). Includes CMYK and Tailwind export.
High-Resolution Palette Export
Instantly download your palette in PNG and SVG formats. Each image includes color names, HEX codes, and an optimized layout for presentation in your brand kits, with automatic contrast calculation.
Design Tokens & W3C Export
Automatically generate your Design System. Assign roles (Primary, Surface, Error) and mathematically calculate state variants (Hover, Pressed). Export the infrastructure in W3C DTCG JSON format, ready for developers, Style Dictionary, and Figma.
