Color is a feeling that the eye reflects to us as a result of the analysis of white light. It is a characteristic and effect produced by the retina, which analyzes the trichromatic color of those who see it, whether it is a pigment or light color. It is a factor in appreciating things and adding contrast between them and the formal aesthetics. Choosing colors in designing things is important. This is because colors do not only show appearance, but also have other goals and meanings. Colors cannot be chosen inappropriately because they have a negative or positive effect depending on how well they are chosen. The design will not succeed if inconsistent colors are chosen.
