Frequently asked questions

Common questions about web colors, CSS color formats, palettes, and contrast.

What is an HTML color picker?

An HTML color picker is a tool that lets you choose a color visually and read the matching HEX, RGB, or HSL code. Web developers use it to find exact colors for backgrounds, buttons, text, borders, and other page elements.

What is the difference between HEX, RGB, and HSL?

HEX is a short web-friendly code like #FF7A59, RGB uses red, green, and blue channel numbers, and HSL describes hue, saturation, and lightness. They can all represent the same color, so the best format depends on how you like to work in CSS.

How do I know if a color has enough contrast?

Check the contrast ratio between your color and a light or dark background. Higher ratios are easier to read, and WCAG AA or AAA ratings help you judge whether the color is strong enough for body text, headings, or decorative accents.

What palette types can this web color picker generate?

This tool generates complementary, analogous, triadic, and split-complementary palettes from your selected color. These palette types help you build color schemes that feel balanced, energetic, or high-contrast.

Is this color picker good for kids learning web development?

Yes. The tool is designed to be simple, visual, and beginner-friendly, so kids can experiment with color theory and see how website colors translate into real CSS values without extra setup.
