Frequently Asked Questions

Are these colour tools free to use?▼
Yes. All tools on Color.Codes.in are completely free with no registration, no watermarks and no usage limits. Use them as much as you need for personal or professional projects.
Do you store the images I upload?▼
No. All image processing happens entirely in your browser using HTML5 Canvas. Your images are never uploaded to our servers. They remain on your device at all times.
What is WCAG contrast compliance?▼
WCAG (Web Content Accessibility Guidelines) defines minimum contrast ratios between text and background colours to ensure readability. Our Contrast Checker tests against all four WCAG 2.1 levels: AA Normal (4.5:1), AA Large (3:1), AAA Normal (7:1) and AAA Large (4.5:1).
How does the Palette Generator choose colours?▼
The generator uses HSL colour theory. Starting from your seed colour, it calculates harmonious combinations by rotating the hue angle on the colour wheel. Complementary uses 180 degrees, Analogous uses 15-30 degree increments, Triadic uses 120 degrees, and Tetradic uses 90 degrees.
Can I find the nearest Pantone or paint shade from the Color Picker?▼
Yes. When you pick a colour, the tool automatically queries our database via AJAX to show the nearest Pantone, RAL, NCS and Indian paint brand matches, ranked by Delta-E colour distance.
