Color Picker & Converter

About This Tool

Colors can be represented in multiple formats, each suited to different contexts. HEX (hexadecimal) is the most common format for CSS and HTML, RGB defines colors by their red, green, and blue light components, and HSL describes colors by hue, saturation, and lightness — which is more intuitive for human perception. This color converter lets you pick any color visually or enter a value in any format and instantly see the equivalent representations in all other formats with a live preview.

Understanding color formats is essential for web developers, UI/UX designers, and digital artists. HEX codes are compact and widely supported, making them the default for design tools and style sheets. RGB is useful for programmatic color generation where you need to manipulate individual channels. HSL is arguably the most intuitive — once you understand that hue represents the color wheel position, saturation controls intensity, and lightness controls brightness, you can create color schemes more naturally.

Common Use Cases

• Converting between color formats for CSS stylesheets, design tools like Figma, and image editing software
• Picking complementary colors for UI design, branding, and data visualization
• Matching colors from screenshots and mockups to precise code values for pixel-perfect implementation
• Quickly converting HEX color codes from design specs to RGB for use in canvas or WebGL APIs
• Generating color palettes by adjusting HSL values such as rotating hue or changing saturation
• Accessibility checking — ensuring sufficient color contrast between foreground and background colors

Pro Tips

• Use HSL for easier color manipulation — adjust hue, saturation, and lightness independently to create harmonious palettes
• HEX is most compact for CSS, while RGB is better for programmatic color generation with JavaScript
• Use the color picker to sample colors from anywhere on your screen (the picker uses the native browser color input)
• Pin frequently used brand colors to your history for quick access across design sessions

Frequently Asked Questions

What is the difference between HEX, RGB, and HSL?

HEX is a compact 6-digit hexadecimal representation (e.g., #FF5733). RGB (Red, Green, Blue) specifies each channel as a number from 0-255. HSL (Hue, Saturation, Lightness) describes color by its position on the color wheel, its intensity, and its brightness — which matches how humans perceive color.

How do I choose a good color scheme?

Start with HSL mode to pick a base hue, then adjust saturation and lightness. Use complementary colors (180 degrees apart on the color wheel) for high contrast, or analogous colors (30-60 degrees apart) for harmonious, low-contrast schemes.

What is the difference between hex #FFF and #FFFFFF?

#FFF is a shorthand notation where each hex digit is doubled, so F becomes FF. Both represent the same color (white). The shorthand version is shorter to write, while the full 6-digit version is more precise and universally supported.

Can I convert colors that include alpha transparency?

This tool focuses on standard RGB colors without alpha. For RGBA or hexadecimal with alpha (like #FF573380), you can extract the RGB components from this tool and add the alpha channel manually in your code.
