WEEKEND EVENT: 2X XP BURSTTechnical Reference
adriantiba.com delivers laboratory-grade color computation entirely in the browser. Every utility below is engineered for designers, brand teams, and frontend developers who require perceptually accurate, standards-compliant color workflows without server latency or data upload.
The Color Blender applies weighted linear interpolation across up to five sRGB inputs, preserving channel integrity inside the standard RGB cube before display encoding. Ratio sliders enforce a 100% total constraint, simulating physical light mixing for UI gradients, brand palettes, and multi-ink print previews. Results are emitted as HEX and RGB for immediate handoff to design systems and CSS custom properties.
Delta E Lab implements the CIE ΔE00 perceptual difference formula to quantify how far two digital colors diverge in human vision, with four-tier diagnostic thresholds. Palette Extractor samples uploaded imagery through 1×1 point, 3×3, and 5×5 averaged eyedropper kernels, mapping screen coordinates back to canvas pixel data for sub-pixel accuracy. Together they form a complete perceptual QA pipeline from image capture to numeric color distance.
Contrast Checker computes W3C relative luminance from foreground and background sRGB values, then evaluates the resulting contrast ratio against WCAG 2.1 thresholds for normal and large text at AA and AAA levels. This gives accessibility auditors an instant, citation-ready compliance snapshot for product UI, marketing pages, and component libraries.
The Color Converter bridges HEX, RGB, HSL, CMYK, CSS LAB, LCH, and OKLCH through a synchronized slider matrix. OKLCH and LAB spaces support modern wide-gamut web pipelines while CMYK and HSL preserve print and legacy authoring workflows. Every field updates bidirectionally in real time, enabling precision migration between design, development, and production color specs.
