### Question
In my project i have computed average color of selected any IMagickImage, and i am trying to match that Average color with another random color. The purpose of my idea to find similar color.

it is generally working with simple RBG colors such as RED GREEN etc, but some times it gives me not appropriate result such as. avg color: Cyan , comparised color: nearly brown etc. it says %95 percen same but not.

i have used simple rgb to hsv comparison but i seems doesn't work
