Generate one cryptographic sRGB candidate with exact HEX and RGB records, then require contrast, non-color, rendering, rights, brand, and user review.
Choose your path
Generate one browser-local random sRGB candidate, expose exact HEX/RGB and generation scope, and route it to target-context accessibility and affected-person review rather than brand or publication approval.
Generate one exact color without a pretend harmonious or brand-aware algorithm.
Generate, copy and save the HEX/RGB candidate, then move to the actual composition and contrast review.
Can explain the random-byte mapping and reject unsuitable candidates freely.
Prevent a swatch from being mistaken for a contrast result.
Pair the candidate with exact foreground/background colors, text size and non-color cues in the target asset.
Approves or rejects the composed use rather than the random value alone.
Separate randomness from distinctiveness, ownership, cultural meaning and sensory needs.
Review candidate use, existing palette/trademark/rights context, target rendering and affected-user feedback.
Can restrict, replace or reject the candidate without a generated recommendation overriding judgment.
Outputs and checklists are planning aids. Review the linked current authorities and the records, terms, instructions, and requirements that apply to your exact situation before a consequential decision.
This tool is part of these guided projects. Each project provides step-by-step instructions with checklists and all the tools you need in one place.

Generate color schemes from a base color. Complementary, analogous, triadic harmony modes. Free design tool with instant browser-based results.
Professional color picker with HEX, RGB, and HSL conversion, WCAG contrast checking, and palette generation. Pick colors and copy CSS-ready values instantly.
Extract dominant colors from any image. Upload a photo and get a color palette with hex and RGB values. Perfect for designers.
The browser supplies three random bytes through Web Crypto; each 0–255 value becomes one sRGB channel and is formatted as six-digit HEX and RGB.
The swatch uses an automatic black-or-white preview label for local readability only. That preview is not a WCAG conformance result for another composition.
Verify the exact foreground/background pair, text size, non-color cues, target rendering, existing brand and rights context, cultural meaning and affected-user needs before use.

Generate and copy a candidate, then deliberately accept, reject or refine it in the real design context.
Save the candidate as unreviewed and complete contrast, non-color and composed-asset review in the Social Content Release Record.
Use a candidate in representative default, hover, focus, disabled and error states, then reject it if the full system loses meaning or readability.
Each activation maps three browser-cryptographic random bytes to red, green and blue channels. The result is an unreviewed candidate—not a palette recommendation, uniqueness claim, brand decision or accessibility approval.
