Title:

There is a collection of colors with several color values (represented by the RBG system). There are now several color values that need to be mapped to a value in the collection. The specific mapping method is to find the one in the collection that has the smallest color distance from it. In the RGB color system, colors are represented by a triple of (Rmaine Greco B), which is an integer between 0 and 255. The distance between two colors is defined as follows: assuming that the triples of two colors are (Ra,Ga,Ba) and (Rb,Gb,Bb) respectively, then the distance between them
