Pick any color and instantly see its HEX, RGB, and HSL values. Perfect for designers and developers.
A color picker is a tool that allows users to select colors and view their representation in different color models. The three most common formats used in web design and development are HEX (hexadecimal), RGB (Red-Green-Blue), and HSL (Hue-Saturation-Lightness). HEX codes are six-character strings starting with a hash that represent colors in web-safe format. RGB defines colors by their red, green, and blue component values ranging from 0 to 255. HSL describes colors by their hue angle on the color wheel (0-360 degrees), saturation percentage, and lightness percentage. Understanding and converting between these formats is essential for anyone working with digital color.
Using our color picker is intuitive. Click on the large color swatch at the top to open your operating system's native color picker dialog. Select any color, and the HEX, RGB, and HSL values will update automatically in real-time. A preview swatch confirms the selected color visually. Each value is displayed in a read-only text field for easy copying. Use the Copy HEX, Copy RGB, and Copy HSL buttons to instantly copy any format to your clipboard. The tool initializes with a default blue color (#2563eb) so you can see the format conversions immediately without needing to select a color first.
Our color picker is a lightweight, browser-based tool that requires no downloads or registrations. It provides instant conversion between the three most important color formats for web development, saving you time and eliminating manual conversion errors. Having color values in multiple formats is useful across different contexts: HEX for CSS stylesheets, RGB for canvas and graphics programming, and HSL for intuitive color adjustments where you need to modify hue, saturation, or lightness independently. Whether you are designing a website, creating digital art, or developing an application, this color picker ensures you always have the right format at your fingertips.
Web designers use color pickers to select and document colors for website projects. Viewing a color in HEX, RGB, and HSL simultaneously makes it easy to write CSS values, create design system tokens, and share specifications with developers.
Building a brand color palette requires precise color selection. Designers pick primary, secondary, and accent colors, then record their values in multiple formats for use across web, print, and digital media. Instant format conversion ensures brand colors are consistently reproduced everywhere.
UI developers frequently convert between color formats when implementing designs. A color picker with instant conversion streamlines the workflow from design tool to code, providing HEX for CSS, RGB for inline styles, or HSL for programmatic color manipulation.
Checking color contrast ratios is critical for web accessibility. Designers use color pickers to identify exact values of foreground and background colors, then verify the ratio meets WCAG guidelines. HSL values are especially useful for adjusting lightness while preserving hue for accessible variations.
WCAG requires a minimum contrast ratio of 4.5:1 for normal text and 3:1 for large text. After picking colors, use a contrast checker to verify your combinations are readable for users with visual impairments. High contrast is both an ethical responsibility and often a legal requirement.
When you need to create color variations, HSL is the most intuitive format. Adjusting the hue rotates through the color spectrum, saturation controls intensity, and lightness determines brightness. This makes it easy to generate shades, tints, and complementary colors without manually calculating RGB values. Use our color picker to experiment with HSL adjustments.
Professional designs use a palette of at least 4 to 6 colors: a primary color, a secondary color, an accent color, and neutral tones. When you select a main color, generate complementary or analogous colors to build a cohesive palette. Consistent use of a defined palette creates visual harmony and strengthens brand recognition.
Approximately 8 percent of men and 0.5 percent of women have some form of color vision deficiency. Avoid relying solely on color to convey information, and use tools that simulate how your palette appears to users with different types of color blindness. Red-green combinations are particularly problematic for the most common forms of color blindness.
| Scheme | Description | How to Create | Best Used For |
|---|---|---|---|
| Complementary | Colors opposite on the wheel | Choose 2 colors 180 degrees apart | High contrast, bold designs |
| Analogous | Colors next to each other | Choose 3 adjacent colors on wheel | Soothing, harmonious layouts |
| Triadic | Three evenly spaced colors | Choose 3 colors 120 degrees apart | Vibrant, balanced designs |
| Monochromatic | Variations of one hue | Adjust lightness and saturation | Clean, minimalist interfaces |
HEX and RGB represent the same colors in different syntax. HEX uses a six-digit hexadecimal number like #2563eb, with each pair of digits representing red, green, and blue values (00-FF). RGB uses decimal notation like rgb(37, 99, 235). Both describe the same colors — choose whichever fits your workflow.
HSL is more intuitive for color manipulation because it separates the color family from its intensity and brightness. To create a lighter color, simply increase the lightness value while keeping the same hue and saturation. This makes HSL the preferred format for generating color scales, themes, and dynamic color adjustments in code.
Most professional designs use 4 to 6 colors: a primary color for branding, one or two secondary colors, an accent color for calls to action, and neutral tones for backgrounds and text. Too many colors creates visual chaos, while too few can appear flat.
Color accessibility ensures designs are usable by people with visual impairments, including color blindness and low vision. This means maintaining sufficient contrast, not relying on color alone to convey information, and testing color choices with accessibility tools. It improves usability for everyone and is often required by accessibility standards.
