🎨 Color Converter — Hex, RGB, HSL, HSV, CMYK
Convert colors between Hex, RGB, HSL, HSV, and CMYK formats in real-time. View a live color swatch, find the closest named color, and check WCAG contrast ratios against white and black backgrounds.
How to Use the Color Converter
Enter a color value in any of the supported formats — Hex, RGB, HSL, HSV, or CMYK. All other fields update automatically and in real-time as you type. A color swatch at the top previews the current color, and the closest named color from the built-in lookup table is displayed below it. Copy any format's value to your clipboard with the copy button next to each input group.
The WCAG contrast ratio section shows how your color performs against white and black backgrounds. A ratio of 4.5:1 or higher meets WCAG AA standards for normal text, while 7:1 or higher meets WCAG AAA standards. This is essential for ensuring your color choices are accessible to users with visual impairments.
Understanding Color Models
Hex (#RRGGBB): A hexadecimal representation of RGB values. Each pair of characters represents red, green, and blue intensity from 00 to FF (0 to 255). Widely used in web design and CSS.
RGB (Red, Green, Blue): An additive color model where values range from 0 to 255. Used by computer monitors, cameras, and digital displays. All colors are created by combining different intensities of red, green, and blue light.
HSL (Hue, Saturation, Lightness): A cylindrical model where hue is the angle on the color wheel (0-360), saturation is the intensity (0-100%), and lightness is the brightness (0-100%). More intuitive for humans to understand and adjust.
HSV (Hue, Saturation, Value): Similar to HSL but value represents the maximum intensity of the color rather than lightness. Commonly used in graphics software and color pickers.
CMYK (Cyan, Magenta, Yellow, Key/Black): A subtractive color model used in printing. Values range from 0 to 100%. Colors are created by subtracting light using cyan, magenta, and yellow inks, with black added for depth.
Color Conversion Methods — Pros and Cons
Hex vs RGB
Pros of Hex: Compact 6-character notation, standard in CSS, easy to copy from design tools, widely used in web development. Cons: No alpha channel in 6-digit form, less intuitive than RGB, hard to adjust mentally.
HSL vs HSV
Pros of HSL: Lightness is more intuitive for creating lighter and darker variants, excellent for design systems and theming, easy to create monochromatic palettes. Pros of HSV: Better for color picking in graphics software, matches how screens display color, preferred for image processing algorithms.
RGB vs CMYK
Pros of RGB: Native to all digital displays, wider gamut than CMYK, no conversion needed for web and screen use. Pros of CMYK: Standard for print production, accurate color matching for physical output, used by all commercial printers.
Accessibility and Color Contrast
Color accessibility is crucial for inclusive design. The WCAG (Web Content Accessibility Guidelines) define contrast ratio requirements to ensure text is readable by users with low vision or color blindness. The minimum contrast ratio for normal text is 4.5:1 (AA), and for large text it is 3:1 (AA). Enhanced requirements are 7:1 (AAA) for normal text and 4.5:1 (AAA) for large text. Use the contrast checker in this tool to verify your color combinations meet these standards before publishing.
