What is Color Contrast?
Color contrast measures the difference in relative luminance between two colors. Sufficient contrast helps text and important visual content remain readable for people with different levels of vision.

| Large text | 3:1 | 4.5:1 |
About Color Picker & Converter
A color picker and converter makes it easy to select, inspect, and convert colors between commonly used formats. Developers and designers often work with HEX, RGB, and HSL values depending on the application, design system, or CSS property they are working with.
DevToolVerse Color Picker & Converter lets you select a color visually or enter an existing color value and instantly see its HEX, RGB, and HSL equivalents. You can also explore shades and tints, view related colors, copy CSS-ready values, and check the contrast between foreground and background colors.
Everything runs directly in your browser, making it quick to experiment with colors without uploading your data or installing additional software.
HEX, RGB, and HSL Color Formats
HEX
HEX is a hexadecimal representation of a color commonly used in HTML and CSS. A standard six-digit HEX color consists of three pairs representing red, green, and blue intensity.
RGB
RGB stands for Red, Green, and Blue. The RGB color model represents a color using three numerical values that describe the intensity of each channel. RGB values are commonly used in CSS with the rgb() function.
HSL
HSL stands for Hue, Saturation, and Lightness. HSL describes colors in terms that can be easier to understand when adjusting the appearance of a color. HSL values are commonly used in CSS with the hsl() function.
Why use different formats? HEX is compact and widely used in web development, RGB is useful when working directly with red, green, and blue channels, while HSL can make it easier to adjust hue, saturation, and lightness. Converting between these formats allows you to use the same color in the format that best fits your workflow.

Limitations & Important Notes
- HEX format: The tool supports 3-digit and 6-digit HEX colors. 4-digit and 8-digit HEX values with alpha channels are not supported.
- Color names: CSS color names are matched exactly against standard CSS color keywords; the tool does not find a closest or approximate color name.
- HSL rounding: HSL values are displayed as whole numbers, so converting RGB to HSL and then back to RGB can produce a small rounding difference of about ±1 per channel.
- Tailwind and WCAG scope: Tailwind matching uses the default Tailwind CSS palette and is an approximate nearest-color match. WCAG contrast results evaluate contrast thresholds but do not represent a complete accessibility assessment.
FAQ
A color picker is a tool that lets you select a color visually and obtain its corresponding color value. Color pickers are commonly used in design and web development.
A color converter converts a color between different formats such as HEX, RGB, and HSL while keeping the underlying color consistent.
Enter a HEX color such as #6366F1 into the Color Picker & Converter. The corresponding RGB value is calculated automatically.
Enter the red, green, and blue channel values, and the tool automatically generates the equivalent HEX color value.
HEX represents colors using hexadecimal red, green, and blue values. RGB directly represents the red, green, and blue channels, while HSL represents hue, saturation, and lightness.
A contrast ratio measures the difference in relative luminance between two colors, typically a foreground and background color. It is used to evaluate text and interface accessibility.
WCAG color contrast requirements provide accessibility guidelines for ensuring that text and other important visual content has sufficient contrast against its background.
For normal-sized text, WCAG AA generally requires a contrast ratio of at least 4.5:1. Large text generally requires at least 3:1.
Yes. HEX, RGB, and HSL values can be used in CSS color properties such as color, background-color, and border-color.
