You can pick a color from your screen in browsers that support the EyeDropper API.
HSL is convenient when you want to keep a color's hue stable while shifting its lightness or saturation. The converter takes an RGB triple and returns the matching CSS hsl() string with hue in degrees and the other two channels as percentages. Common use cases include porting sampled pixel values into stylesheets and building lightness ramps from a single brand color.
HSL is mathematically convenient but not perceptually uniform; for perceptual editing prefer OKLCH on the Color Converter page.
Need more notations? Open the Color Converter for HEX, RGB, HSL, LAB, OKLAB, and OKLCH, or use the Color Contrast Checker to validate foreground/background pairs before shipping.
No. HSL is convenient for stylesheet editing but not perceptually uniform; OKLCH on the Color Converter is a better fit for perceptual ramps.
Greys have no defined hue, so the converter reports 0 and a saturation of 0 to keep the output a valid hsl() value.
Yes. The Other Formats panel always lists hex, RGB, RGBA, HSL, HSLA, HSV, CMYK, and the nearest named color.
