Color Picker & Converter

Color is one of the most powerful tools in a designer's arsenal. Whether you are building a website, designing a logo, or choosing paint for a room, understanding how colors are represented digitally is essential. The three most common color models used on the web are HEX, RGB, and HSL — each offering a different way to describe the exact same color. This free color picker and converter lets you work with all three formats simultaneously, so you always have the value you need.

HEX Color Codes

HEX (hexadecimal) is the format most developers encounter first. A HEX code is a six-character string prefixed with a hash sign — for example, #2563EB. The six characters are actually three pairs: the first two represent red, the middle two represent green, and the last two represent blue, each ranging from 00 (none) to FF (maximum). HEX codes are compact and ubiquitous in CSS, making them the go-to format for web development.

RGB — Red, Green, Blue

RGB describes a color as a mixture of red, green, and blue light, with each channel ranging from 0 to 255. A value of rgb(37, 99, 235) means 37 units of red, 99 of green, and 235 of blue. This additive model mirrors how screens actually produce color — by combining tiny red, green, and blue sub-pixels at varying intensities. RGB is ideal when you need precise control over each light channel, and it is the native format used in CSS functions, image editors, and programming libraries.

HSL — Hue, Saturation, Lightness

HSL rethinks color from a human perception standpoint. Hue is the color's position on the color wheel (0–360 degrees), saturation is how vivid or muted it is (0–100%), and lightness is how bright or dark it appears (0–100%). This makes HSL incredibly intuitive for creating color palettes: to darken a color you simply lower its lightness, and to mute it you reduce the saturation — without having to juggle three separate RGB channels. Designers often prefer HSL for this reason.

How to Use This Tool

Click the color picker to choose any color visually, or type a value directly into the HEX, RGB, or HSL fields. Every input syncs in real time — change one and all others update instantly. The large preview swatch shows your selected color, while the palettes below display harmonious combinations calculated from the HSL color wheel: the complementary color sits 180° opposite, analogous colors are 30° apart, and triadic colors are 120° apart. The shades bar generates five lighter tints and five darker shades, giving you a complete range for gradients, hover states, and UI layering. Click any swatch to copy its HEX value to your clipboard.

Design Tips

• 60-30-10 rule — Use your primary color for 60% of the design, a secondary for 30%, and an accent for 10% to create visual balance.
• Contrast matters — Ensure text and background colors meet WCAG contrast requirements (at least 4.5:1 for normal text) to keep your content accessible.
• Start with HSL — When building a palette from scratch, pick a hue, then vary saturation and lightness to create a cohesive family of colors.
• Use the shade bar — Instead of picking random dark or light variants, use calculated shades for consistent visual rhythm across buttons, borders, and backgrounds.
