rgbToOklch

Function Signature

rgbToOklch(r: number, g: number, b: number): { L: number, C: number, h: number }

Parameters

• r (number): Red channel value.
• g (number): Green channel value.
• b (number): Blue channel value.

Return Value

An OKLCH object with lightness L, chroma C, and hue h in degrees.

rgbToOklch(255, 102, 0);
// { L: 0.6958..., C: 0.2043..., h: 43.49... }

Usage Notes

• OKLCH is useful for palette design because lightness, chroma, and hue can be adjusted separately.
• Gray colors return hue 0 because chroma is effectively zero.
