Explore all toolsA HEX color code is a 6-digit hexadecimal number used to represent colors in web design and digital media. It consists of three pairs of characters representing Red, Green, and Blue values (e.g., #FF5733). HEX codes are the most common format for specifying colors in CSS and HTML.
You can use our HEX to RGB converter tool. Simply enter your HEX code and get instant RGB values. Each pair of HEX digits converts to a number between 0-255 for Red, Green, and Blue channels. For example, #FF5733 converts to rgb(255, 87, 51).
Color contrast is the difference in luminance between foreground and background colors. The Web Content Accessibility Guidelines (WCAG 2.1) require a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text to ensure readability for people with visual impairments. Use our Contrast Checker tool to verify your color combinations.
Use our Color Wheel tool to select a base color, then choose a harmony type (complementary, analogous, triadic, split-complementary, or tetradic) to generate a professionally balanced palette. You can also extract palettes from images using our Palette from Image tool.
RGB (Red, Green, Blue) is an additive color model used for digital screens where combining all colors produces white light. CMYK (Cyan, Magenta, Yellow, Key/Black) is a subtractive color model used in print where combining all colors produces black. Use our Color Converter to switch between formats.
Use our Color Blindness Simulator to preview how your design appears to people with different types of color vision deficiency, including protanopia, deuteranopia, and tritanopia. Our Palette Accessibility Matrix can check all color combinations in your palette at once.
