In eyes of a client, selection of colors or shapes usually is a subjective choice based on some science, but mostly intuition. Designers, especially experienced ones, do this selection automatically, based on expertise and experience. Often, this needs to be revisited and can be one of most contentious subjects of disagreement during any design project.
