The color(s) black, white, purple, gray, blue, green, red, orange, indigo, violet is/are claimed as a feature of the mark.
The mark consists of The mark is a mirrored image showing the exponential growth in both directions, left and right, and the center of the mark has no coloring or shading and as you get further out to the ends the color scale increases until you have complete saturation at the furthest ends. The tool is used to conduct comparative judgement surveys for matching candidates into an index. It uses placement, as well as amplitude, and color saturation to indicate preference for one item (word, picture or image) A person does not have to be able to read in order to use the tool. It is an exponential growth curve in the direction to the right of center and its inverse (inverse proportionality to the left of center, making one continuous mark.
