Generate returns the base color, lighter and darker blends, a complementary hue, and a neutral gray. Check the resulting colors in the actual interface before adoption.</p><h2>How the result is produced</h2><p>The browser parses the HEX channels, blends the base color toward white or black, rotates hue in an HSL approximation for the complement, and formats the results back to six-digit HEX values.</p><h2>Test examples</h2><p>#336699 produces a darker blend, lighter blend, complementary suggestion, and neutral companion. The output is a starting palette, not a claim that the colors meet an accessibility target.</p><h2>Limitations</h2><p>The generator uses a simple sRGB/HSL approximation and does not model perceptual color spaces, brand guidance, contrast for every text size, color vision deficiency, print profiles, or wide-gamut displays.</p><h2>Privacy and processing</h2><p>The color value is processed locally in the browser and is not uploaded.</p><h2>Related guide</h2><p><a href="https://nofyi.com/generated-color-palettes-need-accessibility-review/">A generated color palette still needs accessibility review</a></p><h2>Related tools in this category</h2><ul class="nfaf-related-tools"><li><a href="https://nofyi.com/tools/hex-rgb-color-converter/">HEX and RGB Color Converter</a><span>Enter a HEX color such as #336699 and get its red, green, and blue channels.</span></li><li><a href="https://nofyi.com/tools/wcag-color-contrast-checker/">WCAG Color Contrast Checker</a><span>Enter foreground and background HEX values to see the ratio and WCAG-style pass guidance.</span></li></ul><h2>Documentation</h2><ul><li><a href="https://www.w3.org/TR/css-color-4/" rel="nofollow noopener" target="_blank">https://www.w3.org/TR/css-color-4/</a></li><li><a href="https://www.w3.org/WAI/WCAG22/Understanding/contrast-minimum.html" rel="nofollow noopener" target="_blank">https://www.w3.org/WAI/WCAG22/Understanding/contrast-minimum.html</a></li></ul><p class="nfaf-disclosure">This page describes the implementation shipped with the NOFYI Tool Factory.
