from person to person (mood, age, etc.), varying environments,
such as lightness and color, can make it difficult to communicate
and document color and color differences.
If you are involved in the creation or design of visual documents, an understanding of color will help when incorporating it into your own designs. Choices regarding color often seem rather mystical, as many seem to base decisions on nothing other than “it looks right.” Although often told I had an eye for color, the reason why some colors worked together while others did not always intrigued me and I found the study of color theory fascinating.
