Color Harmonies
Convert colors between HEX, RGB, HSL, HSV, and other formats. Pick colors with a visual color picker, generate harmonious palettes, and check contrast ratios for accessibility.
Color Conversion and Accessibility Tools for Web and Graphic Design
Colors are specified in many formats depending on context. HEX (hexadecimal, e.g., #FF5733) is the most common on the web and in CSS; RGB (red, green, blue channels from 0-255) is used in CSS and image processing; HSL (hue, saturation, lightness) is intuitive for human color selection; HSV (hue, saturation, value) is common in design software.
Converting between these formats is essential for designers and developers: you might find a color in a design tool (HSL), need to copy it as HEX for CSS, or convert RGB from an image to adjust it in a color picker.
Accessibility is equally critical: contrast between text and background must meet WCAG standards (4.5:1 for normal text, 3:1 for large text). Many developers don't realize their color combinations fail accessibility checks until a testing tool flags it. OmniToolsKit's color converter includes real-time contrast checking and color-blindness simulation showing how your palette appears to people with different types of color vision deficiency (protanopia, deuteranopia, tritanopia).
Converting Design Tool Colors to CSS
Designers work in HSL or pick colors visually; developers need HEX or RGB for CSS. Paste a color from Figma or Adobe XD and instantly convert it to the format your codebase uses.
Generating Color Palettes
Start with a base color and generate complementary, triadic, or analogous palettes. Ensures color harmony across your design and provides CSS variables for your entire palette.
Checking WCAG Contrast Compliance
Test text and background color combinations against WCAG AA, AAA, and Enhance Contrast standards. Catches accessibility failures before they reach users.
- 1
Enter Color in Any Format
Paste a color value: HEX (#FF5733, #000), RGB (rgb(255, 87, 51)), HSL (hsl(10, 100%, 60%)), or a CSS color name. The tool auto-detects the format.

View Conversions to All Formats
Instantly see the same color in HEX, RGB, HSL, HSV, and CSS name formats. Copy any format with one click for use in CSS, HTML, design tools, or screenshots.
- 3
Use Visual Color Picker for Selection
Click the color picker to select visually using hue/saturation/lightness sliders. This is fastest when you're refining a color without starting from a specific value.
- 4
Check Contrast and Export CSS
Enter text and background colors to instantly check WCAG contrast scores. Export a complete color palette as CSS variables (custom properties) ready to copy into your stylesheet.
HEX/RGB/HSL/HSV Format Conversion
Instantly convert colors between all major web formats. HEX is fastest to copy for CSS; HSL is easiest to adjust lightness; RGB is used in image processing.
Visual Color Picker and Palette Generation
Drag sliders to pick any color, or generate complementary, triadic, and analogous palettes automatically. Ensure color harmony without guesswork.
Real-Time WCAG Contrast Checking
Test text/background combinations instantly against WCAG levels (AA, AAA). Guarantees your site is accessible to people with low vision or color-blindness.
Color Blindness Simulation
See how your colors appear to users with protanopia, deuteranopia, tritanopia, and monochromacy. Ensures your design isn't relying on color alone for information.
