Color Code Converter (All Formats)

Welcome to the Color Code Converter (All Formats), a free online tool that converts any color value into every common format at once. Paste a HEX code, an RGB triplet, an HSL or HSV definition, a CMYK quartet, or even a CSS named color — and instantly read off the equivalent values, see a live preview swatch, check WCAG accessibility contrast, and explore a generated designer palette of complementary, triadic, analogous, tints, and shades.

Why use an all-in-one color converter?

Most color converters online only handle one direction (HEX to RGB, or RGB to CMYK), forcing you to chain together multiple tools when you need a full picture. This converter accepts every common format in a single field, auto-detects which format you typed, and returns all five at once with a live preview — saving you several steps when you bridge between web, mobile, print, and design tools.

Supported input formats

What is the difference between HSL and HSV color models?

Both HSL and HSV describe a color through three intuitive channels — Hue, Saturation, and a third lightness-related value — but they differ in that third channel.

• HSL — Hue, Saturation, Lightness: lightness ranges from 0% (pure black) through 50% (the most vivid version of the hue) up to 100% (pure white). HSL is preferred in CSS because it makes lightening or darkening a color symmetrical and predictable.
• HSV / HSB — Hue, Saturation, Value (Brightness): value ranges from 0% (pure black) up to 100% (the fullest, most saturated version of the hue). HSV is the model behind the color pickers in Photoshop, Figma, and most desktop design tools.

For example, a fully saturated red is hsl(0, 100%, 50%) in HSL but hsv(0, 100%, 100%) in HSV. The same color in two different mental models — both useful, depending on whether you are thinking like a CSS author or like a painter.

Why do my CMYK values look slightly different from print software?

RGB is an additive model used by screens, while CMYK is a subtractive model used by printers. The mathematical conversion this tool performs is a quick approximation that does not include any ICC color profile, ink coverage limits, or paper-specific adjustments. For production print work, always rely on your design software's color-managed CMYK profile (such as US Web Coated SWOP v2 or Coated FOGRA39). Use this converter as a fast reference when you simply need a CMYK quartet that is "close enough" for early-stage design conversations.

How does the WCAG contrast check work?

The Web Content Accessibility Guidelines define a contrast ratio between two colors based on their relative luminance — a perceptual brightness model that weights green more heavily than red, and red more heavily than blue. The ratio runs from 1:1 (no contrast at all) to 21:1 (pure black on pure white).

• AAA — ratio ≥ 7:1, meets the strictest accessibility level for body text
• AA — ratio ≥ 4.5:1, the minimum for body text in most regulations
• AA Large — ratio ≥ 3:1, sufficient for large text (18pt+ or 14pt bold) and graphical UI elements
• Fail — ratio < 3:1, do not use this combination for text

The tool computes contrast against pure white and pure black, then highlights the better choice as your default text color when this hue is used as a background.

Does the converter generate a color palette?

Yes. After every conversion the tool builds a designer palette from the same hue, including:

• Complementary — the color directly opposite on the wheel (180° hue rotation), useful for high-contrast accents
• Triadic — two colors evenly spaced 120° apart, balanced and vibrant
• Analogous — neighboring hues at ±30°, useful for harmonious gradients and backgrounds
• Tints — three lighter variations (same hue, higher lightness)
• Shades — three darker variations (same hue, lower lightness)

Click any palette swatch to instantly load it into the converter as a new starting point — perfect for iterating quickly on a brand color, an icon set, or a UI theme.

How to use this tool

1. Enter or pick a color — type any value (HEX, RGB, HSL, HSV, CMYK, or a CSS color name) into the input field, or click the small color swatch to open your browser's native color picker.
2. Convert — click the Convert button. The tool auto-detects the format you supplied and computes every other format.
3. Copy what you need — click any one-tap copy button next to a format value. The button briefly shows a checkmark to confirm the value is on your clipboard.
4. Check accessibility — review the WCAG contrast ratios against pure white and pure black to confirm whether the color is readable as text or background.
5. Explore the palette — click any swatch in the designer palette section to convert it, expanding your design exploration without leaving the page.

Practical use cases

For web developers

• Convert a HEX from a Figma comp into hsl() for use with CSS custom properties and modern theming systems
• Generate rgba() values for translucent overlays directly from a brand HEX color
• Verify that a brand color meets WCAG AA on white backgrounds before shipping

For graphic designers

• Translate a CSS color from a website into a CMYK approximation for print mockups
• Build a tonal scale (tints and shades) from a single starting hue
• Find a complementary or triadic accent without leaving the browser

For UI & product designers

• Cross-walk between HSV (Figma's picker) and HSL (CSS) when documenting design tokens
• Identify the best text color (black vs white) automatically for any background
• Quickly bookmark or share a converted color via the URL of the result page

Tips for best results

• Be flexible with separators — the parser accepts commas, spaces, or slashes inside the parentheses, so rgb(79 70 229) works as well as rgb(79, 70, 229).
• Use percentages where appropriate — rgb(31%, 27%, 90%) is valid; the tool converts percentages into 0–255 internally.
• Try CSS named colors — over 140 names work, including modern additions like rebeccapurple.
• Read the channel bars — the visual breakdown of red/green/blue and CMYK channels makes it easy to see which inks dominate the print version of the color.
• Treat CMYK as a guide only — open the result in your color-managed print software for the final, accurate value.

Frequently asked questions

Do I need to include the # symbol when entering a HEX value?

No. Both #4f46e5 and 4f46e5 are accepted. The leading # is optional.

Are 4-digit and 8-digit HEX values (with alpha) supported?

The parser will accept them, but the alpha channel is dropped during conversion because RGB, HSL, HSV, and CMYK in their classic forms do not carry alpha. The tool focuses on the color portion only.

Can I share or bookmark a converted color?

Yes. The form submits via GET, so the URL contains the color you converted. Copy the page URL after conversion to share or bookmark the exact result page.

Why are some HEX values shown in uppercase letters?

The output canonicalizes HEX to uppercase (e.g. #4F46E5) which is the convention used in many design and brand-style guides. You can paste it back in lowercase if you prefer — both are equivalent.

Does it work on mobile devices?

Yes. The interface is fully responsive and the form, palette, and contrast cards reflow into single-column layouts on smaller screens for a comfortable touch experience.
