I want to thank my friends Danmin Fu and Guoling Gu for developing this app. If you see any issues, please contact me. 

Any color can be quantified with its hue (H), (from 0 to 360), Saturation (S) or chroma (from 0 to 100), and value (V) (from 0 to 100). HSV are called the coordinates of the color. If you know HSV of a color, you can do many analysis about this color.


If you have a color sample, how do you obtain the HSV of this color? This app will be the tool you do a measurement with. Let's say you just bought a new tube color and you want to know its HSV.


Before you start the measurement, you must have a good white light, and calibrate your computer display.


First you prepare a color sample by painting the color on a white card, maybe 2" x 2" in size. Secondly, you make the color sample partially cover the color swatch (now is red) of this app. Use a good white light to lit the color sample. Third you adjust the H, S, and V slider to change the color on the swatch until the swatch color matches the color sample. Now the values of H, S, and V on the slider is the HSV of the color sample.
