Your Essential Color Tool for Web Design and Development

Working with color is fundamental to every design and development workflow. Whether you are fine-tuning a brand palette, converting a color value from a design mockup, or experimenting with new color combinations, this free color picker gives you everything you need without leaving your browser.

Understanding Color Formats

Different tools and platforms expect colors in different formats. Here is what each one means:

FormatExampleUsed In
HEX#FF5733CSS, HTML, design tools
RGBrgb(255, 87, 51)CSS, JavaScript, image processing
HSLhsl(14, 100%, 60%)CSS, color theory, accessibility
HSB/HSVhsb(14, 80%, 100%)Photoshop, Figma, design tools

HEX is the most common format for web development, representing red, green, and blue channels as two-digit hexadecimal numbers. RGB uses decimal values from 0 to 255 for each channel. HSL stands for hue, saturation, and lightness, making it the most intuitive format for manually adjusting colors. HSB (hue, saturation, brightness) is preferred by most graphic design applications.

Why HSL Is the Designer’s Best Friend

While HEX and RGB are widely used, HSL is arguably the most practical format for making color adjustments. Want a lighter shade? Increase the lightness value. Need a muted tone? Decrease saturation. The hue value maps directly to the color wheel, making it easy to find complementary or analogous colors by rotating the hue by fixed degrees.

Accessibility and Color Contrast

Choosing colors is not just about aesthetics. Web Content Accessibility Guidelines (WCAG) require sufficient contrast between text and background colors. A minimum contrast ratio of 4.5:1 is needed for normal text and 3:1 for large text. When picking colors for your interface, always verify that your chosen combinations meet these thresholds.

From Picker to Production

The one-click copy feature means you can go from color selection to working code in seconds. Pick a color, copy the HEX or RGB value, and paste it directly into your stylesheet, Tailwind config, or design token file. No manual conversion or lookup tables required.

Frequently Asked Questions

What color formats are supported?

The tool supports HEX (e.g., #FF5733), RGB (e.g., rgb(255, 87, 51)), HSL (e.g., hsl(14, 100%, 60%)), and HSB/HSV formats. You can input a color in any format and instantly see the equivalent values in all other formats.

Can I pick a color from my screen?

If your browser supports the EyeDropper API (Chrome and Edge), you can sample any color visible on your screen. Otherwise, use the visual color picker to select your desired color interactively.

How do I convert RGB to HEX?

Simply enter your RGB values into the input fields and the HEX code will appear automatically. For example, RGB(255, 87, 51) converts to #FF5733. Each RGB channel (0-255) maps to a two-digit hexadecimal value.

Is there a way to save colors for later?

You can copy any color code to your clipboard with one click. The tool also displays your recently picked colors so you can quickly return to a previous selection during your session.
