Yellow Being the color of the sun, yellow brings a smile. Color that is easily seen from a long distance (so it is often used for traffic signs) and communicates fun, friendliness, pleasure and energy (who doesn’t need more yellow in his life?) Yellow can also be associated with mental clarity and intelligence (again, who doesn’t need more yellow?) Even so, yellow is also a careful color used in safety jackets, police safety tapes, and dangerous areas. You need to use Coloring Ideas Abstract Usable for free usage in coloring your day.
