Color Picker & Converter

Free Color Picker & Converter — HEX, RGB, HSL & HSV

Color management is a daily challenge in web design and development. Picking the right color, converting between formats, finding complementary and analogous colors, and generating tints and shades for a complete color palette all require tools that work fast. This free Color Picker converts between HEX, RGB, HSL, and HSV instantly, generates complementary colors, and provides CSS-ready color values for immediate use in your stylesheets.

Use the visual color picker to select any color by hue, saturation, and lightness. Or enter a known value in any format — HEX (#FF5733), RGB (255, 87, 51), or HSL (11°, 100%, 60%) — and all other formats update instantly. Get the CSS snippet, color name (if it matches a CSS named color), and palette suggestions including complementary, analogous, and triadic colors.

Color contrast is also critical for accessibility. The WCAG 2.1 AA standard requires a contrast ratio of at least 4.5:1 for normal text. The color picker shows contrast ratios against white and black backgrounds so you can verify accessibility compliance as you design.

Color Format Reference

HEX. 6-digit hexadecimal code: #RRGGBB. Each pair ranges from 00–FF (0–255 decimal). Most common format in CSS and design tools. Supports shorthand 3-digit notation (#RGB) when pairs are identical digits.

RGB. rgb(R, G, B) — three values 0–255. Also supports rgba(R, G, B, A) for opacity (0–1). Direct mapping to screen phosphor values.

HSL. hsl(H, S%, L%) — Hue (0–360°), Saturation (0–100%), Lightness (0–100%). Most intuitive for designers — vary lightness to get tints and shades of the same hue.

HSV/HSB. Hue, Saturation, Value (Brightness). Used in Photoshop's color picker. Similar to HSL but Value controls the mix of pure color vs black rather than the midpoint between black and white.
