Solution - In graph , the chromatic number is atleast three since the vertices , , and are ...The four-color theorem states that any map in a Plane can be colored using four-colors in such a way that regions sharing a common boundary (other than a single point) do not share the same color. This problem is sometimes also called Guthrie's Problem after F. Guthrie, who first conjectured the theorem in 1853.Additionally, there are tools available to convert images to how they look for different types of color vision deficiencies. The most common form of color vision deficiency involves differentiating between red and green. Thus, avoiding colormaps with both red and green will avoid many problems in general. References#A Five-Color Map. The five color theorem is a result from graph theory that given a plane separated into regions, such as a political map of the countries of the world, the regions may be colored using no more than five colors in such a way that no two adjacent regions receive the same color.
