🚀 How to Use
Three ways to pick a color
1

Method A: Visual Palette

Click anywhere on the color spectrum/gradient palette to select a hue. Drag the saturation/brightness slider to fine-tune your selection.

2

Method B: Enter a Value

Type a known color code directly — paste a HEX code, or enter RGB / HSL values into the input fields. The picker updates to show your color instantly.

3

Method C: Pick from Image

Upload any image, then click on any pixel to extract that exact color. Get the HEX, RGB, and HSL values for colors you see in photos, screenshots, or logos.

4

Copy Your Color Values

Click the copy icon next to any format (HEX, RGB, HSL, CMYK) to copy it to your clipboard and paste directly into your code or design tool.

✨ Pro Tips
🖥️

Screen vs Print Colors

RGB/HEX is for screens. CMYK is for print. Always convert to CMYK before sending to a printer to avoid color shift surprises.

Check Accessibility

After picking text and background colors, check their contrast ratio. WCAG AA requires at least 4.5:1 contrast for small text.

🎯

Use HSL for Theming

When building dark/light themes, HSL is easiest — just adjust L (lightness) while keeping H and S the same for consistent tones.

Save Your Palette

Note your chosen HEX codes in a shared doc or design token file so your whole team uses identical colors consistently.

❓ Frequently Asked Questions
What is a HEX color code? +
A HEX code is a 6-character code representing a color using hexadecimal numbers (0–9 and A–F). For example, #FF0000 is pure red. The first two characters represent Red, the next two Green, and the last two Blue values.
What's the difference between RGB and RGBA? +
RGB stands for Red, Green, Blue. RGBA adds a fourth channel — Alpha — which controls opacity or transparency. For example, rgba(124, 58, 237, 0.5) is the same purple but at 50% transparency. Use RGBA in CSS when you need semi-transparent colors.
Why does my screen color look different when printed? +
Screens use RGB (light-based) and printers use CMYK (ink-based). These are different color models with different color ranges (called "gamut"). Some vibrant screen colors simply can't be reproduced accurately in print — always convert to CMYK and request a proof from your print shop.
Can I pick a color from any image or website screenshot? +
Yes! Upload any image (PNG, JPG, WebP) to the image color picker feature and click on any pixel to extract its exact color. For picking from any website on your screen, browser extensions like "ColorZilla" (Chrome/Firefox) let you pick colors directly from live web pages.
What is HSL and when should I use it? +
HSL stands for Hue, Saturation, and Lightness. It's more intuitive than RGB — you start with a hue (the base color), adjust saturation (how vivid), and lightness (how bright or dark). HSL is especially useful in CSS for creating color themes, tints, and shades systematically.
How do I match a brand's exact color? +
Most brands publish their official color values in brand guidelines. Check the company's brand guide for their official HEX, RGB, or Pantone values. If you have a logo image, use the "Pick from Image" feature to extract the color, but note that image compression can slightly alter values — always prefer the official guide when available.
