Color Picker

What's the difference between HEX, RGB, and HSL?

HEX uses hexadecimal notation (#FF0000), RGB uses decimal values (255,0,0), and HSL uses hue/saturation/lightness (0°,100%,50%). All represent the same red color.

Which color format should I use?

Use HEX for CSS and web design (most common), RGB for graphics software, and HSL when you need to adjust brightness or saturation programmatically.

How do I choose colors that work well together?

Use the color wheel theory: complementary colors (opposite), analogous colors (adjacent), or triadic colors (120° apart) create pleasing combinations.

What about color accessibility?

Ensure sufficient contrast between text and background colors. WCAG guidelines recommend at least 4.5:1 contrast ratio for normal text and 3:1 for large text.
