color questions

1. What are the 3 primary colors?  
The three primary colors are Red, Green, and Blue.

2. How are secondary colors created?

4. What is the difference between subtractive and additive color models? 

additive colors are colors which are "pure", i.e. colors add up to form white light. A Red light looks Red because it emits Red light.

while subtractive colors are "impure". You perceive Red pigment to be Red because it reflects Red light and absorbs everything except Red light falling on it.

5. How can color affect our perception? 

A website might have content that is eloquent and clear, but the color choices for background and other elements could send a contradictory message. Many companies choose their colors based off of personal preference or the corporate logo, but fail to realize that the website says much more than what is presented on the conscious level.  Design elements such as color choice that reach visitors on the subconscious level deliver just as strong of a message as written content.

6. How does one color affect another? 

Two colors, side by side, interact with one another and change our perception accordingly. The effect of this interaction is called simultaneous contrast. Since we rarely see colors in isolation, simultaneous contrast affects our sense of the color that we see. For example, red and blue flowerbeds in a garden are modified where they border each other: the blue appears green and the red, orange. The real colors are not altered; only our perception of them changes. This effect has a simple scientific explanation that we will uncover.
