Choose color scheme carefully
Designers must have a general understanding about which colors and color combinations are right for a particular situation. Colors are bound with concrete feelings, so choosing the wrong ones may not support the message you want to convey to your audience. Here I have listed the psychological meaning of some of them:
White: light, goodness, purity or innocence
Black: power, elegance, formality or death
Red: joy, passion, sensitivity or love
Orange: energy, happiness, desire or pleasure
Yellow: sunshine, joy, happiness, intellect or energy
Green: growth, harmony, freshness, stability or endurance
Blue: trust, wisdom, confidence, intelligence or faith
Purple: power, luxury, ambition, extravagance or creativity
The wrong color choice leads to a distrustful message—similar to the difference between speech and behavior in human interaction.
Using multiple colors is harder—consider how they affect each other. Only your eyes can help you find a good balance. Some sites like ColorShemer and Kuler have color schemes that could assist you in the choice of your color palette. But they can also limit your experiments, so try to minimize their use. Color combinations are subjective and what works for one may not work for another.
