This code you can to convert rgb color to hsv color ranges in python, this interface is easy to use there. you only need to have installing python and opencv in your pc
the necessary libraries are :
PIllOW, TKINTER, IMULTIS, OPENCV = CV2, NUMPY.
For exameple I need to find the green color is HSV scale but I don't know th values. I can find the green color on this way in the interface there are six trackbar H min , H max, S min, S max, V min and V max I can move the values my recomendation is S max = 255 V max = 255 and move the others trackbar for find the color you want.
In this picture I found the green color moving the values Hmin = 50, Smin = 55, Vmin = 58, Hmax = 97, Smax = 255, Vmax = 255.
