Summary

The LCH (Lightness, Chroma, Hue) color space was created to be perceptually uniform and easy for humans to work with, particularly for accent colors in design systems. The LCH color space is designed to provide a more accessible alternative to RGB and HSL, which have limitations in terms of human perception and manipulation. While RGB and HSL are easier to use, they have flaws that make them less suitable for accessibility requirements. In contrast, the LCH color space offers improved accessibility features, such as retaining original saturation values and providing a more accurate representation of colors outside the sRGB range. However, there are trade-offs associated with using LCH, including limitations on chroma and lightness maximum values and potential hue offset issues when converting from HSL to LCH.
