Personal preference should not be the deciding factor when choosing colors; rather, factors relating to the target audience and the purpose of website should be the deciding factors. This is because studies generally show that different sexes prefer different colors. For example, women tend to like blue, pink, purple, and green better than gray, orange, and brown, while men tend to like blue, green, and black better than purple, orange, or brown. Similarly, adults prefer different colors and color combinations compared with children. Children tend to like vibrant colors, while adults tend to like more subdued colors.
