However, the graph obtained from K n by attaching a degree-one vertex to each vertex of K n has a significantly smaller distinguishing number, despite having the same symmetry group: it has a distinguishing coloring with ⌈ ⌉ colors, obtained by using a different ordered pair of colors for each pair of a vertex K n and its attached neighbor.
Color is an element consisting of hues, of which there are three properties: hue, chroma or intensity, and value. [3] Color is present when light strikes an object and is reflected back into the eye, a reaction to a hue arising in the optic nerve.

A split-complementary (also called compound harmony) color scheme comprises three colors, namely a base color and two colors that are 150 degrees and 210 degrees apart from the base color. The split-complementary color scheme has the same sharp visual contrast as the complementary color scheme but has less pressure. [further explanation needed]

Since "visual appearance" is a general concept that includes also various other visual phenomena, such as color, visual texture, visual perception of shape, size, etc., the specific aspects related to how humans see different spatial distributions of light (absorbed, transmitted and reflected, either regularly or diffusely) have been given the ...
