This paper presents the method to get the equations that transform a color space of n independent primary colors to the HSIn color system (H: hue, S: saturation, I: intensity); n indicates the number of bands and the shape of the HSIn space. For n=3 the structure is a double triangular pyramid, for n=4 it is the structure of the double pyramid tetrangular, and so on.
Key words: HSI color space, euclidian space
