Frequently Asked Questions

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

HEX uses a six-character hexadecimal code (e.g., #FF5733), RGB defines colors by red, green, and blue channel values from 0–255, and HSL uses hue (0–360°), saturation, and lightness percentages. All three can represent the same colors — they are just different notations.

How do I convert a HEX color to RGB?

Split the six-digit HEX code into three pairs, then convert each pair from hexadecimal to decimal. For example, #FF5733 becomes R=255, G=87, B=51. Online color pickers perform this conversion instantly.

When should I use HSL instead of HEX or RGB?

HSL is more intuitive for designers because you can adjust lightness or saturation independently without affecting the hue. It makes creating color palettes and hover-state variations much easier than manually tweaking HEX or RGB values.

Can I use an online color picker for accessibility compliance?

A color picker helps you select colors, but you also need a contrast checker to verify WCAG compliance. Look for tools that show the contrast ratio between foreground and background colors to ensure your text meets the minimum 4.5:1 ratio.
