Free Online Color Space Converter
Convert colors between different color spaces (RGB, HSV, HSL, CMYK, LAB) with real-time updates and a color wheel.
How It Works
Select or input a color, and instantly view its equivalent values in other color spaces. You can also modify the values directly in any color space field, and the results will update automatically. Clicking the green button next to each value copies it to your clipboard for easy use.
Frequently Asked Questions
What is a Color Space?
A color space is a specific organization of colors used to represent color in digital formats. Different color spaces are used for screens, printing, and image processing.
Why Convert Between Color Spaces?
Different devices and applications use different color spaces. Converting between them ensures accurate color reproduction across screens, printers, and design software.
Which Color Spaces Are Supported?
Our tool supports RGB, HEX, HSV, HSL, CMYK, and LAB, allowing seamless conversion between them.
What is RGB?
RGB (Red, Green, Blue) is an additive color model used in screens and digital displays. Colors are created by combining different intensities of red, green, and blue light.
What is HEX?
HEX (Hexadecimal Color Code) is a shorthand representation of RGB colors in web design. It consists of six characters, such as #FF0000 for red.
What is HSV?
HSV (Hue, Saturation, Value) represents colors in terms of their shade (hue), intensity (saturation), and brightness (value). It is useful for color selection in design tools.
What is HSL?
HSL (Hue, Saturation, Lightness) is similar to HSV but uses lightness instead of brightness, making it more intuitive for adjusting colors in design applications.
What is CMYK?
CMYK (Cyan, Magenta, Yellow, Black) is a subtractive color model used in printing. Instead of adding light like RGB, it subtracts colors from white to create different hues.
What is LAB?
LAB (CIELAB) is a perceptual color space designed to approximate human vision. It separates color into lightness (L) and two color channels (A and B), making it useful for color correction.
What is Contrast Ratio?
Contrast ratio measures the difference in brightness between two colors. It is crucial for accessibility, ensuring that text remains readable against its background.
How is Contrast Ratio Calculated?
In our tool, the contrast ratio is calculated between your selected color and white (`#ffffff`). The calculation follows the WCAG (Web Content Accessibility Guidelines) formula:
Contrast Ratio = (L1 + 0.05) / (L2 + 0.05)
Where:
- L1 = Relative luminance of the lighter color (white, `#ffffff`)
- L2 = Relative luminance of the selected color
Why is Contrast Ratio Important?
A high contrast ratio ensures readability, especially for people with visual impairments. WCAG recommends the following minimum contrast levels:
- 4.5:1 for normal text
- 3:1 for large text (18pt or bold 14pt)
- 7:1 for enhanced accessibility
Can I Compare Against Other Background Colors?
Currently, our tool calculates contrast only against white (`#ffffff`). In future updates, we may allow users to select custom background colors for contrast analysis.
How Accurate Are the Conversions?
The conversions use industry-standard formulas to ensure precision, but minor variations may occur depending on display calibration and color gamut differences.
Do You Store My Color Data?
No, all conversions happen directly in your browser. We do not store or transmit any color data to a server.
