How does the Color Picker and Palette Generator work?

Everything runs 100% locally inside your web browser. You can pick colors via the native system picker or eyedropper, fine-tune channels using HEX, RGB, and HSL sliders, generate mathematically harmonious palettes (monochromatic, analogous, complementary, triadic, tetradic), extract dominant color schemes from uploaded images, and test foreground/background combinations against WCAG 2.1 accessibility guidelines.

Are my uploaded images saved or sent to any server?

No. Image color extraction uses an in-browser HTML5 canvas and median-cut quantization. Your images never leave your device, never get uploaded to any backend server, and are discarded immediately when you close or refresh the page.

What color harmony modes are available?

The generator supports Monochromatic (lightness tints and shades of your hue), Analogous (adjacent colors separated by 30°), Complementary (the exact opposite 180° hue), Split-Complementary (150° and 210° accents), Triadic (three colors spaced evenly at 120°), and Tetradic / Double-Complementary (four colors spaced evenly at 90°). You can adjust the palette size between 3 and 6 colors.

What do WCAG AA and AAA ratings mean in the Contrast Checker?

The Web Content Accessibility Guidelines (WCAG) 2.1 define contrast thresholds based on relative luminance. Level AA requires at least 4.5:1 for normal text (under 18pt) and 3.0:1 for large text (18pt+ or 14pt bold). Level AAA requires a stricter 7.0:1 for normal text and 4.5:1 for large text. Meeting these standards ensures your website is accessible to users with low vision or color deficiencies.

Can I export palettes for CSS, Figma, or design systems?

Yes. You can copy the entire palette formatted as HEX values, RGB triplets, or ready-to-paste CSS custom properties (--color-1, --color-2, etc.). You can also download a comprehensive JSON file containing full color tokens and metadata.

Is this tool completely free to use?

Yes, the Color Picker & Palette Generator is 100% free with unlimited usage and no account or credits required.
