Here are a few thoughts, as I've studied this issue for many years. In fact I have a presentation I give on this subject as part of the ACM distinguished lecturer program and the IEEE Computer Society's distinguished visitor program. 1) There actually have been academic programs called computer science engineering, but the name never caught on.
The color black represents strength, seriousness, power, and authority. Black is a formal, elegant, and prestigious color. Authoritative and powerful, the color black can evoke strong emotions and too much black can be overwhelming. In heraldry, black is the symbol of grief.
If there is a color that symbolizes denial it would be gray. Gray is not really a color but just a value of white mixed with black. Gray is commonly used as to represent the unknown. It is a symbol of questionable morality. Designers use gray to make something fade into the background. When a person is in denial, they may relate to the color gray, because they may be wrong/bad, but they feel as if they are right/good.
