Free Color Code is your all-in-one color code solution — a free, browser-based toolkit that lets you find, convert, generate, and manage every color code format you need for modern web design and development. Whether you're a front-end developer writing CSS, a UI designer building design systems, or a content creator matching brand colors, our suite of ten precision tools handles every color workflow without leaving your browser.
Stop manually calculating values. Our color code converter transforms HEX color codes, RGB color codes, HSL color codes, and CMYK instantly with pixel-perfect accuracy. Paste any color code hex value like #0070F3 and get the exact color code RGB equivalent rgb(0, 112, 243), color code HSL hsl(222, 91%, 48%), and CMYK breakdown in milliseconds. The bidirectional converter works as a hex to RGB, RGB to HEX, HSL to HEX, and color code calculator all in one.
Browse our curated color code chart with names featuring 140+ standard web color codes — from color code red (#FF0000) and color code blue (#0000FF) to color code green, color code black, color code white, color code yellow, color code orange, color code purple, and color code pink. Each entry displays the color code hex, color code RGB, color code HSL, and human-readable name, making it the ultimate color code reference and color code guide for quick lookup.
Need to extract an exact color code from a screenshot, logo, or photo? Our color code finder and color code picker let you upload any image and click to identify the precise color code from image at any pixel. The color code identifier returns HEX, RGB, HSL, and color name instantly — perfect for reverse-engineering brand palettes or matching UI elements. It's the fastest color code lookup tool for designers who need to find color code from image assets without guesswork.
Create professional color code palettes in seconds with our free color code generator. Choose from monochromatic, analogous, complementary, triadic, and tetradic harmony rules, or lock specific color codes and let the algorithm complete the scheme. Export production-ready CSS color code variables, Tailwind config, or SCSS maps directly. Browse color code combinations from our curated trending palettes — Modern SaaS, Cyber Neon, Sunset Ember, Nordic Forest — each balanced for accessibility and visual hierarchy.
Every tool outputs color code for HTML and color code for CSS in formats developers actually use: #HEX, rgb(), rgba(), hsl(), hsla(), CSS custom properties, and framework-ready tokens. The gradient generator produces copy-paste linear-gradient() and radial-gradient() declarations. The contrast checker validates WCAG 2.1 AA/AAA ratios against text and UI components in real time.
Join 50,000+ designers and developers who trust Free Color Code as their daily color code reference. Whether you need a quick color code conversion, a full color code palette for a new project, or an exact color code match from a design file, Free Color Code delivers professional results instantly — no installation, no account, no friction.

A HEX (hexadecimal) color code is a 6-digit alphanumeric representation preceded by a hash symbol (e.g., #FF5733). The six digits split into three two-digit byte pairs: Red, Green, and Blue. Each byte ranges from 00 (0 intensity) to FF (255 max intensity). A three-digit shorthand like #F53 automatically duplicates each character to #FF5533.
HEX is best for design tokens and CSS stylesheets due to its compact brevity. RGB (rgb(255, 87, 51)) is ideal when programmatically manipulating opacity in WebGL or canvas using alpha channels. HSL (hsl(11, 100%, 60%)) is king for building dynamic UI color ramps, shades, and interactive hover states because tweaking lightness doesn't distort base hue.
Start by selecting a single anchor brand hue with strong contrast against white and black. Then apply the 60-30-10 UI rule: 60% neutral surface canvas (clean whites or deep slates), 30% secondary structural color (borders, cards, headers), and 10% high-intent accent for primary CTAs and interactive highlights.
The Web Content Accessibility Guidelines (WCAG) dictate minimum contrast ratios to guarantee content is legible for the 300+ million people globally with vision impairments. Level AA mandates a minimum ratio of 4.5:1 for body text and 3.0:1 for large text (18pt+) and UI borders. Level AAA demands a stringent 7.0:1 ratio.
Quick answers to common questions about color code formats, conversion, and tools.
rgb(red, green, blue). For example, pure red is rgb(255, 0, 0), white is rgb(255, 255, 255), and black is rgb(0, 0, 0). RGB is the native color model for screens and digital displays.#. Each pair of digits represents Red, Green, and Blue intensity from 00 to FF (0-255 in decimal). For example, #FF0000 is red, #00FF00 is green, and #0000FF is blue. HEX is the most common color code for HTML and CSS color code usage due to its compact format.hsl(hue, saturation%, lightness%). For example, hsl(0, 100%, 50%) is pure red. HSL makes creating color code palettes and variations (shades/tints) much easier.#RRGGBB. RGB uses base-10 decimal: rgb(R, G, B). They convert 1:1: #0070F3 = rgb(0, 112, 243). HEX is shorter for CSS; RGB is readable and supports alpha via rgba(). Our color code converter transforms between them instantly.rgb(0, 112, 243) into our color code converter — it outputs #0070F3. (3) Upload an image to the color code finder and click the color — the HEX appears immediately. All methods are free, instant, and work offline.#0070F3) or HSL color code into Free Color Code's color code converter — the RGB color code (rgb(0, 112, 243)) appears instantly. Or use the color code picker to select a color visually, or upload an image to the color code finder and click to sample. The tool also shows rgba() with alpha channel for transparency.hsl(222, 91%, 48%)). The color code picker also lets you adjust HSL sliders directly to see real-time changes. HSL is ideal for creating systematic color code palettes — modify lightness for shades/tints, shift hue for complementary colors, or adjust saturation for muted/vivid variants.
