Color Picker

About Color Picker

A color picker is an essential tool for web designers, frontend developers, and digital artists. Colors in digital design are represented numerically using several standard formats: HEX (hexadecimal), RGB (Red Green Blue), and HSL (Hue Saturation Lightness). Each format serves different purposes and workflows.

HEX (#RRGGBB) is the most common format in web development — it is compact, familiar, and directly supported in CSS. Each pair of characters represents a color channel value from 00 (0) to FF (255). The format can be extended to 8 characters (#RRGGBBAA) to include alpha transparency.

RGB defines colors as combinations of red, green, and blue light, each with values from 0 to 255. RGB is intuitive if you think of mixing light — rgb(255, 0, 0) is pure red, rgb(0, 255, 0) is pure green, and rgb(0, 0, 255) is pure blue. CSS supports both rgb() and rgba() functional notations.

HSL describes color in a more human-intuitive way: Hue (0-360 degrees on the color wheel, where 0/360 is red, 120 is green, 240 is blue), Saturation (0-100%, from gray to full color), and Lightness (0-100%, from black to white). HSL is often easier to use when creating color palettes since you can adjust hue while keeping saturation and lightness consistent.

This color picker lets you visually select colors and instantly see the corresponding HEX, RGB, and HSL values. The opacity shade strip shows how your color appears at different transparency levels — useful for UI design considerations like overlays, shadows, and layered elements.
