OKLCH is a newer color model that prioritizes how humans perceive colors, making it easier for designers to create and manipulate color palettes. It operates on three values: Lightness, Chroma, and Hue, similar to the LCH model, but it uses the OKLab color space underneath. Lightness ranges from 0 to 1 or 0% to 100%, while Chroma indicates color intensity and Hue is measured in degrees from 0 to 360. One of OKLCH's main benefits is its ability to maintain consistent brightness across different colors, allowing designers to create uniform color palettes more easily than with older models like HSL. In terms of color gradients, OKLCH calculates transitions based on lightness, chroma, and hue, which can lead to smoother gradients. However, this can also result in unexpected colors due to the circular nature of hue. To counter this issue, many design tools opt for the OKLab model for gradient calculations, which provides more consistent results. The model also supports a broader color gamut than traditional sRGB, allowing for colors that modern displays can render more vividly, especially on screens that support Display-P3. OKLCH can define colors outside the range of real screens, meaning some defined colors may be clipped when displayed, leading to noticeable differences from what was intended. To manage browser compatibility, developers can use the CSS @supports directive to provide fallback options. This ensures that if a browser does not support OKLCH, it can revert to sRGB versions of the colors, maintaining visual consistency whenever possible.
