How do I convert a HEX color to RGB by hand?
A HEX color is just an RGB color written in base-16. Split the six digits into three pairs: the first pair is red, the second green, the third blue. Convert each two-digit pair from hexadecimal to decimal (0 to 255) to get the RGB value. For example, #3B82F6 splits into 3B, 82, and F6; in decimal those are 59, 130, and 246, giving rgb(59, 130, 246). A three-digit shorthand like #F30 expands by doubling each digit to #FF3300, and an eight-digit HEX8 code adds a final pair for the alpha (transparency) channel. The reverse works too: divide each RGB channel into its hexadecimal pair and join them. Doing this by hand is slow and error-prone, so paste any HEX or RGB value into the converter above and read the exact equivalent instantly, alongside HSL, HSV, CMYK, LAB, and the nearest named CSS color.
What is the difference between HSL and HSV color models?
Both describe a color by hue (0 to 360 degrees on the color wheel) and saturation, but they treat brightness differently. HSL uses lightness, where 0% is black, 100% is white, and 50% is the most vivid version of the hue. HSV (also called HSB) uses value or brightness, where 0% is black and 100% is the brightest version, but pure white only appears when saturation is also 0%. In practice, HSL is intuitive for nudging a color lighter or darker on the web, while HSV matches the picker behavior in most graphics apps like Photoshop. Because the two define brightness with different formulas, the same color carries different saturation numbers in each model, so you cannot just copy the values across. Enter any color above and the tool shows HSL, HSLA, and HSV/HSB side by side, along with HEX, RGB, and CMYK, so you can compare every model at a glance without doing the math.
Why do colors look different in CMYK than on screen?
Screens use RGB, an additive model that mixes red, green, and blue light, while printers use CMYK, a subtractive model that layers cyan, magenta, yellow, and key (black) ink on paper. RGB can produce bright, saturated colors, especially in vivid greens, oranges, and blues, that simply fall outside the smaller range of inks CMYK can reproduce. Those out-of-gamut colors get clipped to the nearest printable equivalent, which usually looks duller or slightly shifted in hue. This is why a glowing on-screen blue can print muddy and a neon green loses its punch on paper. Converting to CMYK before sending artwork to print gives you a realistic preview of how the color will translate and lets you adjust early. Paste your HEX or RGB color above to see its CMYK percentage breakdown instantly, so there are no surprises at the press.
How do I check if two colors have enough contrast for accessibility?
Contrast is measured as a ratio between the relative luminance of a foreground and background color, ranging from 1:1 (identical) to 21:1 (black on white). The Web Content Accessibility Guidelines (WCAG 2.1) require at least 4.5:1 for normal text and 3:1 for large text (18pt, or 14pt bold) to meet Level AA, rising to 7:1 and 4.5:1 for the stricter Level AAA. Higher ratios mean text is easier to read, especially for users with low vision or on glare-prone screens. Calculating luminance and the ratio by hand is tedious, so use the Contrast tab in this tool instead: enter your text and background colors and it computes the exact ratio, shows a live text preview on your chosen background, and displays pass or fail badges for each WCAG level, so you can confirm a color pair is legible before it ships rather than after a complaint.
What are complementary, triadic, and analogous colors?
These are color harmonies based on positions around the 360-degree color wheel. Complementary colors sit directly opposite each other (180 degrees apart), like blue and orange, creating high contrast and energy. Triadic colors are spaced evenly at 120 degrees, giving a balanced, vibrant set of three. Analogous colors are neighbors on the wheel (typically within about 30 degrees), producing calm, cohesive palettes since they share an underlying hue. Other schemes include split-complementary and tetradic (a four-color square). Choosing a harmony is a reliable shortcut to a palette that looks intentional rather than random, since the relationships are grounded in the geometry of the wheel. This tool generates all of these schemes from any base color you enter, plus tints (mixed toward white), shades (toward black), and tones (toward gray), and lets you click any swatch to make it the new active color and keep exploring from there.

About the Color Converter
The Color Converter turns a single color into every format you might need for the web, print, or design work. Type a HEX code, an rgb() value, an hsl() value, or even a CSS color name like tomato, and the tool instantly shows the same color expressed as HEX, HEX8, RGB, RGBA, HSL, HSLA, HSV/HSB, CMYK, LAB, LCH, and the nearest CSS named color. You can also click the swatch to open your browser's native color picker, drag the alpha slider for transparency, or hit the shuffle button for a random color.
It's built for the people who juggle color codes daily: front-end developers translating a designer's HEX into CSS variables, UI designers checking how a brand hue reads in HSL, and print-bound work that needs a CMYK breakdown. Everything runs entirely in your browser. Nothing you enter is uploaded or stored on a server, there's no sign-up, and no app to install.
Every color format in one place
Each format answers a different question, and the Color Converter shows them side by side so you don't have to do the math:
- HEX / HEX8 — the six-digit web standard (e.g.
#3b82f6), plus an eight-digit variant that bakes the alpha channel into the code. - RGB / RGBA — red, green, and blue from 0 to 255, with an optional alpha value from 0 to 1 for transparency.
- HSL / HSLA — hue (0 to 360 degrees), saturation, and lightness, the most intuitive model for nudging a color lighter, darker, or more vivid.
- HSV/HSB — hue, saturation, and value (brightness), the model behind most graphics-app color pickers.
- CMYK — cyan, magenta, yellow, and key (black) as percentages, the starting point for anything headed to a printer.
- LAB / LCH — CIE perceptual color spaces designed so equal numeric steps look like equal visual steps to the human eye.
Copy any single value with one click, grab them all with Copy All, or export the full list as a plain-text file.
Check accessibility with the WCAG contrast checker
A separate Contrast tab calculates the contrast ratio between a foreground and background color and tells you, at a glance, which accessibility thresholds it passes. The Web Content Accessibility Guidelines (WCAG 2.1) set the bar at 4.5:1 for normal text and 3:1 for large text (18pt or larger, or 14pt bold) to meet Level AA, rising to 7:1 and 4.5:1 for the stricter Level AAA. The tool shows a live text preview on your chosen background plus pass/fail badges for each level, so you can confirm a color pair is legible before it ships rather than after a user complains.
Build palettes with harmonies, tints, and shades
Picking one good color is easy; building a set that works together is the hard part. The Converter generates classic color-wheel harmonies from your base hue, including complementary (180° opposite), triadic (120° apart), split-complementary, tetradic (90° square), and analogous (neighboring) schemes. It also produces tints (mixed toward white), shades (toward black), and tones (desaturated toward gray) so you can map out an entire range from a single starting color. Click any generated swatch to load it as the new active color and explore from there.
Private, fast, and always available
Because every conversion, contrast calculation, and palette is computed on your own device, the tool works the moment the page loads and never sends your colors anywhere. A short session history keeps your recently used colors a click away, and a CSS named-colors reference lets you load any standard web color by name. Open the Color Converter, enter a color, and read off whichever format your next step needs.
