1. Some of the factors that influence the psychological impact that color has on people are age, gender, culture, and life experiences.
2.Each color has a different affect on people and how it makes them feel for example...
Red; red will give a sense of power, danger, strength, passion or fire
Green; green will make you feel at peace and give more of a cool, natural feel
Violet; violet will give off a dramatic and dignified feeling
3. Secondary colors are colors that are made when you mix an equal amount of two primary colors mixed together; the secondary colors are:
Orange: made up of red and yellow
Green: made up of yellow and blue
Violet: made up of blue and red
4. The primary color is always stated first in a tertiary color
5. Intensity is the brightness or dullness of a color; value is the lightness or darkness.
6. A tint is when white is added to the color; a shade is when black is added to the color; a shade is when grey is added to the color.
7. you neutralize a color by adding black white or grey to the color.
8. There are two color groups, warm and cool: warm colors would be colors such as red and orange; cool colors would be colors like blue and purple
9. There are seven color harmonies listed below and how you use them:

•  monochromatic; a single color hue
• complementary color; using colors that are directly across one another on the color wheel are complementary colors
• slip complementary colors; using a hue with two hues adjacent to its compliment 
• double complementary; using two colors and their compliments
• analogous colors; using related hues from the color wheel
• triadic colors; using any three colors that are equally spread out form each other
• neutral colors; combinations of black white and grey even though they are not "hues"

10. Some things that would effect the color harmony a person chooses would be their all around mood, lifestyle, gender, age and much more!
11. Some of the factors that play into harmonies use din planning would include the space you have to decorate , and who you are decorating it for.
12. If you were dealing with someone who can not differ between two colors you should always just fill the space with a happy color because what are the odds if you put yellow in the wall they will see black? They would maybe see a color like green or purple, another happy or bright color.
13. I would suggest a color that never seems to disappoint maybe a shade of green or rustic orange they both give off a relaxing feeling but would go along with the northern feeling the room gives off.
