Instant Universal Color Conversion (12 Formats Supported)
Our intelligent engine automatically detects your input and instantly converts it across 12 different color standards like Hex to rgb, Rgb to Cmyk, Cmy to Hsl etc. Simply type, paste, or use the Color Picker to select a shade.
New: Advanced Opacity & Transparency Control
Unlike standard converters, our tool includes a dedicated Opacity Slider next to the color picker.
Control Alpha Channel: Adjust opacity seamlessly from 0.00 (Transparent) to 1.00 (Opaque).
Real-Time Updates: Moving the slider instantly generates 8-digit HEX codes (
#RRGGBBAA), RGBA, and HSLA values.
We support precise conversion for the following formats:
HEX: Supports both standard 6-digit and modern 8-digit HEX with Alpha (e.g.,
#FF573380).RGB & RGBA: Red, Green, Blue (with dedicated Alpha transparency).
HSL & HSLA: Hue, Saturation, Lightness + Alpha channel.
HSV / HSB: Hue, Saturation, Value (Brightness).
CMYK & CMY: Cyan, Magenta, Yellow, Key (Black) for print design.
LAB: CIELAB color space with 2-decimal precision for professional accuracy.
XYZ: The CIE 1931 standard. Includes a “Range 0-1” toggle for scientific 4-decimal precision (0.0000–1.0000).
- OKLAB & OKLCH: The modern, perceptually uniform color spaces ideal for CSS and design systems, ensuring accurate, consistent brightness across all hues.
How to Convert Colors with Transparency (Step-by-Step)
Input Your Color: Paste any code (e.g.,
#FF5733,hsla(9, 100%, 60%, 0.5)) or use the visual Color Picker.Adjust Opacity: Use the Opacity Slider next to the picker to set the transparency level (0.00 to 1.00). Watch the HEX code transform into an 8-digit format automatically.
View Conversions: Instantly copy the converted codes for RGBA, HSLA, CMYK, LAB, and more.
Set Precision (Optional): For scientific use, check the “XYZ range 0 to 1” box to switch XYZ values to a 0-1 scale with 4-decimal precision.
Generate Palette: Scroll to the Monochromatic Palette section to see 10 variations of your base color.
Save or Download: Click “Save” to keep the color for later, or “Download” to get a PDF, JPG, or SVG file containing all technical data.
Advanced Accessibility & Contrast Checker
Design with inclusivity in mind. Our built-in Color Contrast Checker ensures your designs meet WCAG (Web Content Accessibility Guidelines) standards.
Detailed Ratio Analysis: Get the exact contrast ratio between your background and foreground.
Real-time Preview: Visualize the result with an interactive “Aa” text preview on your selected main color.
Pass/Fail Indicators: Instantly know if your color combination is readable for visually impaired users.

Frequently Asked Questions (FAQ)
Q: Why should I use Oklch or Oklab instead of HSL?
Oklch and Oklab are modern, “perceptually uniform” color spaces. Unlike HSL, where blue might look darker than yellow at the same “lightness” value, Oklch ensures that colors with the same values actually look equally bright to the human eye. This makes them the new standard for modern CSS and UI design systems.
Q: Why do I need to convert RGB to CMYK for printing?
RGB is for screens (emitting light), while CMYK is for physical ink (reflecting light). If you send an RGB file to a printer, the colors often come out muddy or dull. Converting to CMYK allows you to see a more accurate simulation of how your design will look on paper before you print.
Q: What is the difference between HSL and HSV (HSB)?
While both define colors by Hue and Saturation, they handle brightness differently. HSL (Lightness) treats white as 100% lightness. HSV (Value) treats the pure, colorful pigment as 100% value, and white is achieved by lowering saturation. Designers often prefer HSB for painting, while web developers prefer HSL.
Q: What makes CIELAB (LAB) and XYZ different from other formats?
Formats like RGB and CMYK are “device-dependent” (they look different on different screens). LAB and XYZ are “device-independent.” They describe exactly how the human eye perceives color, regardless of the screen. This makes them the perfect “bridge” format for converting colors accurately between other standards.
Q: Can I use this tool to generate CSS variables?
Yes. Since our tool provides outputs for HEX, RGB, HSL, and modern Oklch simultaneously, you can copy these values directly into your CSS :root variables to ensure your website supports both legacy browsers and modern color spaces.
Q: How does the Opacity Slider affect the color codes?
When you adjust the slider, the tool automatically updates formats that support transparency. It generates RGBA and HSLA values (changing the ‘A’ value from 0 to 1) and converts your standard HEX code into an 8-digit HEX code (adding the alpha value to the end, e.g., #FF0000 becomes #FF000080 at 50% opacity).
Q: What is the difference between HSL and HSLA?
HSL stands for Hue, Saturation, and Lightness. HSLA adds an Alpha channel, which controls the opacity/transparency of the color. Our tool converts between both instantly.
Q: What are 8-digit HEX codes (HEXA)?
An 8-digit HEX code is an extension of the standard 6-digit HTML color code that includes transparency (Alpha). The format is #RRGGBBAA. The last two digits represent the opacity level, where 00 is fully transparent and FF is fully opaque. This allows web designers to define transparency directly in the HEX format without using RGBA.
Q: Is HSL better than HEX for web design?
Many developers prefer HSL (Hue, Saturation, Lightness) over HEX because it is more intuitive. In HSL, you can easily adjust the brightness or shade of a color just by changing the percentage values, whereas changing a HEX code requires calculating a new mix of Red, Green, and Blue hexadecimal values.
Q: Why does the XYZ code change when I check the “Range 0 to 1” box?
By default, we show XYZ values tailored for standard visual design (often scaled 0-100 with 2 decimals). Checking “Range 0 to 1” switches the output to the scientific standard (0.0 to 1.0) and increases accuracy to 4 decimal places, which is preferred for 3D rendering and mathematical calculations.
Q: Can I convert a transparent HEX code back to RGB?
Yes! If you paste an 8-digit HEX code (like #00FF0080), the tool instantly detects the transparency and converts it to the correct RGBA format (e.g., rgba(0, 255, 0, 0.5)).
Q: Is the contrast checker WCAG compliant?
Yes, the Contrast Checker calculates the exact contrast ratio and helps you determine if your color pairings meet WCAG AA and AAA standards for accessibility.
Q: Does the tool save my colors if I close the browser?
Yes, if you click the “Save” button, your colors are stored in your browser’s Local Storage (No Login Required). They will appear in the “Saved Colors” section when you return.
