When you need to ensure consistent color display across different devices, this tool provides real-time, two-way conversion between RGB (Red, Green, Blue) and CIELab (a device-independent color space) using precise algorithms. CIELab is a device-independent color space based on human visual perception, where L* represents lightness (0-100), a* represents the red-green axis (-128 to 127), and b* represents the yellow-blue axis (-128 to 127), accurately reflecting how the human eye perceives color differences.
A: Two formats are supported: the CSS standard rgb(255,0,0) or pure numeric values like 255,0,0 (value range 0-255).
A: Color gamut differences may cause an error of about 0.5%. The limited color gamut of RGB cannot fully cover the theoretical color space of CIELab.
RGB components must be within the 0-255 range, and the CIELab L* value is limited to 0-100. Exceeding these ranges will result in conversion errors. It is recommended to process sensitive color data locally; this web page does not store any input records.
The printing industry recommends prioritizing CIELab values to ensure color consistency. A typical example: web red rgb(255,0,0) corresponds to Lab(54,80,69). Please note that monitor color gamut limitations may cause slight differences between the conversion results and the actual printed output.
