A color converter translates a single color between the different encoding systems used in web design, print, and digital art. Whether you start with a hex code from a designer's style guide, an RGB triplet from CSS, or an HSL value from a color picker, you can instantly see how that same color is represented in every other format.
This tool supports six formats: RGB (red, green, blue), Hex (hexadecimal shorthand of RGB), HSL (hue, saturation, lightness), HWB (hue, whiteness, blackness), CMYK (cyan, magenta, yellow, key/black), and Natural Color (NCol), a human-readable angle-based system. It also identifies the nearest CSS named color when the match is close.
Additive model used in screens. Each channel ranges from 0 to 255. Mixing all three at full intensity gives white.
Compact six-digit (or three-digit) hexadecimal encoding of RGB. Widely used in CSS and HTML. Example: #ff6347 for tomato.
Describes color as a hue angle (0–360°), saturation percentage, and lightness percentage. Natural for human perception.
Alternative to HSL. Uses hue angle plus whiteness and blackness percentages, making it easy to tint and shade.
Subtractive model used in color printing. Cyan, magenta, yellow, and black inks combine to produce a full spectrum.
Natural Color system proposed by W3C. Encodes hue as a letter (R, Y, G, C, B, M) plus a percentage offset, plus whiteness and blackness.
The iconic blue from Google's logo palette. In RGB it is (66, 133, 244); in HSL approximately 217°, 89%, 61%. A vivid, accessible shade widely recognized in Material Design.
One of CSS's most distinctive named colors. RGB (255, 99, 71) — a warm, saturated red-orange. Often used for call-to-action buttons and alert indicators.
A cyan-teal hue (RGB 32, 178, 170, HSL 177°, 70%, 41%) inspired by coastal waters. Common in nature-themed and wellness web designs.
A medium purple (RGB 155, 89, 182) from flat-design palettes. In CMYK roughly 15% C, 51% M, 0% Y, 29% K. Used in creative and tech branding.
Choose the input format that matches the color code you have (Hex, RGB, HSL, HWB, CMYK, or NCol).
Enter the color values in the input fields. Results update instantly — no button needed.
The converter normalizes all inputs to an internal RGB representation, which is the universal pivot format.
From that RGB triplet, all other formats (Hex, HSL, HWB, CMYK, NCol) are calculated using standard mathematical formulas.
The color name lookup scans 148 CSS named colors and returns the closest one if it is within a visual-difference threshold of about 30 RGB units.
For web CSS use Hex or RGB for exact specification; prefer HSL when you want to adjust lightness or saturation programmatically.
CMYK values are estimates — actual print color depends on ink, paper, and color profile. Always request a print proof.
HWB is the most intuitive format for tinting (increase whiteness) or shading (increase blackness) a hue.
The NCol hue letter closest to 'R0' is pure red at 0°. Increase the number to advance clockwise: 'R50' is halfway to yellow.
When copying a hex code from a design tool, the '#' prefix is optional — this converter accepts either form.
Both use a hue angle, but the second and third parameters differ. HSL uses saturation (color purity) and lightness (midpoint between black and white). HWB uses whiteness (amount of white mixed in) and blackness (amount of black mixed in). HWB is often considered more intuitive because increasing whiteness or blackness directly tints or shades the color.
Screens use additive light (RGB) while printers use subtractive ink (CMYK). The gamuts don't perfectly overlap, so some vivid screen colors cannot be reproduced with standard CMYK inks. This converter calculates a mathematical CMYK equivalent, but the final printed result will depend on ink type, paper, and color management profiles.
Natural Color is a W3C-proposed color encoding that represents hue as a letter (R, Y, G, C, B, M) denoting the nearest primary/secondary, plus a percentage offset to the next sector, followed by whiteness and blackness percentages. For example, R0 0% 0% is pure red, Y50 0% 0% is mid-way between yellow and green.
Yes. Use the 'Find by CSS Name' search box to type any CSS named color. The converter will load its RGB values and show all format equivalents instantly.
Hex, RGB, and HWB conversions are lossless within integer rounding. HSL and NCol involve floating-point arithmetic and are rounded to one decimal place. CMYK values are approximate because the RGB-to-CMYK formula used here is device-independent and does not account for specific ink profiles.
Only 148 standard CSS named colors are included. If the entered color is more than ~30 RGB units away from any named color, no name is shown. Most mid-range or custom brand colors will not have an exact named match.
Color representations may vary between devices due to display calibration, color profiles, and rendering engines. CMYK values are mathematical approximations and may differ from physical print results.
