So, I've put some keywords for each color based on a research for the meaning of them. Here's the result:

Red

Passion, love, rebellion, power and excitement.

Orange

Summer, retro, mellow, friendly and inviting.

Yellow

Happiness, cheer, fun, energetic, young and friendly.

Green

Environment, nature, profit, growth and trust.

Blue

Peace, calm, intelligence, freedom, royalty, progress and trust.

Purple

Royalty, mysticism, romance, elegance and style.

Brown

Tradition, earthy, cottage and colonial.

The thing about mixing colors is fantastic. For example, if you mix the peace of blue and the excitement of red, you'll get movement in monotony, antagonistic concepts where one completes another and vice versa. The resultant color is Purple and the resultant concept is mysticism, mystery and even spiritual (religions).
