I'm not its developer nor am I affiliated with the developer. I found this tool years ago and still use it from time to time. If you want to use Eyedropper on windows with a tool like Paint, you can do the math with the ratios explained above, or just use the RGB value whenever possible. Hue is endpoint-exclusive (because 360° = 0°) whereas Saturation and Luminance are endpoint-inclusive (because 1.0 is achievable). In Windows, the Hue, Saturation, and Luminance ranges are rescaled so that they go from 0 to 240.

On the other hand, Saturation and Luminance are floating point Reached because Hue is cyclical, so a value of 360° is equivalent toĠ°. Range for Hue is an angle, normalized to be greater than or equal toĠ° and strictly less than 360°. The reasoning is explained on the windows blog. Some tools like Paint on windows will give slightly different values: Note that HSB format gives standard values, which are: Works on windows XP, vista, 7, 8, 10 and probably beyond that.Ĭlarification on values returned by the HSB option
