We associate certain meanings with each color we see. This is called "Color Symbolism".
A few years back I painted a series of paintings based on these meanings. All 8 paintings in this series were painted on 8" x 24" stretched canvases and the title of the series is "Impact". This series is based on the symbolic meaning of colors.
These paintings are done in a realistic-abstract style in which there is a suggestion about reality but it's not very descriptive. From a distance, these paintings look like a patch of vibrant color and create an impact on the viewer's mind, but on a closer look, some suggestive details narrate the story of the painting.
Let's look at each painting and the symbolism behind that color.
Similarly, every other color evokes certain feelings in our minds.
So, next time you want to create a painting or a presentation, make sure you use the appropriate colors in the right proportion. This will certainly help you in creating the feelings you want in the viewers' minds.
