Overview

What Is the Color Picker & Converter?

The Color Picker & Converter is a free browser-based tool that lets you select any color — visually or by entering exact values — and instantly see its representation in five industry-standard formats: HEX, RGB, HSL, HSV/HSB, and CMYK. Every field is bidirectional: change a single number and all other formats recalculate in real-time.

Beyond conversion, the tool generates a 10-step tint-and-shade palette, displays complementary, triadic, and analogous color harmonies, and calculates WCAG 2.1 contrast ratios so you can verify accessibility before you ship.

Designers use it to translate Figma or Photoshop colors into CSS-ready values; developers grab the ready-made CSS snippet and paste it straight into their stylesheets. The CMYK view helps print designers approximate screen colors for press output without a separate tool.

Everything runs in your browser — no server calls, no analytics, no sign-up. Your color history is kept only in memory for the current session. Close the tab and nothing remains.

Use Cases

Common scenarios where a color picker and converter saves time and simplifies your workflow

Web Development

Quickly convert design-spec HEX colors to RGB or HSL for CSS, Tailwind config, or CSS-in-JS. Copy ready-made CSS snippets directly into your stylesheets.

Graphic Design

Convert colors between screen (RGB, HEX) and print (CMYK) formats. Generate harmonious palettes for brand identity, posters, and social media graphics.

Accessibility Auditing

Use the built-in WCAG contrast checker to verify that text colors meet AA or AAA standards against their backgrounds before shipping to production.

UI / UX Prototyping

Explore tints, shades, and color harmonies to build cohesive UI palettes. Click any swatch to jump to that color and iterate on your design system interactively.

Print & Packaging

Convert screen colors to CMYK values for accurate print reproduction. Avoid costly color mismatches by checking CMYK breakdowns before sending files to press.

Education & Learning

Understand how color models relate to each other. Change one HSL slider and watch RGB and CMYK update — ideal for students learning color theory and digital media.

FAQ

FAQ

Frequently asked questions about the Color Picker & Converter

Q1. What color formats does this tool support?
The tool supports five formats: HEX (#RRGGBB), RGB (0–255 per channel), HSL (hue 0–360, saturation 0–100%, lightness 0–100%), HSV/HSB (hue 0–360, saturation 0–100%, value 0–100%), and CMYK (0–100% per channel). All formats are bidirectional — change any one and the rest update instantly.
Q2. Is my data private?
Yes. All color calculations happen entirely in your browser using JavaScript. No color data, history, or preferences are sent to any server. Close the tab and everything is gone.
Q3. How does the WCAG contrast checker work?
The tool calculates the relative luminance of your color and compares it against pure white (#FFFFFF) and pure black (#000000) using the WCAG 2.1 contrast ratio formula. A ratio of 4.5:1 or higher passes AA for normal text, 7:1 passes AAA, and 3:1 passes AA for large text.
Q4. What is the difference between HSL and HSV?
Both use Hue (0–360°) but differ in the other two axes. HSL uses Saturation and Lightness — 50% lightness is the pure hue, 0% is black, 100% is white. HSV uses Saturation and Value — 100% value is the brightest, and reducing saturation moves toward gray. Designers often prefer HSL for CSS, while HSV is common in image editors like Photoshop.
Q5. How accurate is the CMYK conversion?
The tool uses the standard mathematical RGB-to-CMYK formula, which gives a good approximation for screen-to-print conversion. For production printing, actual CMYK values depend on the ICC color profile of your printer and paper. Use these values as a starting point and fine-tune with a calibrated workflow.
Q6. Can I generate a full color palette?
Yes. The Shades & Tints bar automatically generates five lighter and five darker variations of your current color. You also get complementary, triadic, and analogous harmony palettes. Click any swatch to switch to that color and explore further.
Q7. What is the nearest CSS color name?
The tool compares your selected color against all 148 CSS named colors (like 'CornflowerBlue', 'Tomato', 'SlateGray') and shows the closest match by Euclidean distance in RGB space. It is an approximation — useful for quick reference, not an exact match unless your color is one of the named 148.
Q8. Does the color history persist between sessions?
No. The history of your last 10 colors is stored only in the browser's component state for the current session. Refreshing the page clears it. This is intentional — no data is written to localStorage, cookies, or any server to preserve your privacy.
