Features
Omni-Directional

Native Picker
Click the visual box to bring up the eyedropper tool and select colors from your screen.
Print Ready
Accurately converts digital screen colors (RGB) into printer-safe ink formulas (CMYK).
CSS Formatted
Outputs strings like hsl(200, 50%, 50%) so you can paste directly into your stylesheet.
Understanding Color Formats
- HEX (Hexadecimal): The most common format used in web design (e.g.,
#FFFFFF). It uses a base-16 number system to define the red, green, and blue light intensities. - RGB (Red, Green, Blue): Defines the same color as HEX but uses a 0 to 255 decimal scale (e.g.,
rgb(255, 255, 255)). Highly useful in JavaScript animations. - HSL (Hue, Saturation, Lightness): The most human-readable format. Instead of guessing how much green to add, you simply change the Hue angle (0-360) and adjust the Saturation or Lightness percentages.
- CMYK (Cyan, Magenta, Yellow, Key/Black): A subtractive color model used exclusively for physical printing. It calculates the exact percentage of physical ink needed on white paper to produce the color.
The UI Design Toolkit
If you are designing a user interface, grab your HSL color from this tool and test it against our CSS Triangle Generator. Need to create a smooth fade between two colors? Paste your HEX codes into our CSS Gradient Generator. For manipulating photos to match your new brand color, use the CSS Filter Generator.
Frequently Asked Questions
Why does the CMYK color look different when printed?
Monitors emit light (RGB), while paper absorbs light and reflects the remainder (CMYK). Some highly vibrant RGB colors (like neon green) cannot be reproduced using standard CMYK ink, resulting in a slightly muted printed color.
Does this support Alpha/Opacity channels?
Currently, this tool handles solid colors (no alpha channel). If you need an alpha channel, convert to RGB or HSL here, and simply add the a and the decimal to the end in your code (e.g., rgba(0,0,0, 0.5)).
Why use HSL instead of HEX?
HSL is much easier to manipulate in CSS. For example, if you want a button to get slightly darker on hover, you can just lower the Lightness percentage in HSL. Doing that in HEX requires a complex calculator.
