to categorize the responses to color we can say it comes from psychological, symbolic, historical and traditional, cultural, creative, political and geographical associations. Identifing color associations of cultures completely is a demanding task. The same way that naming colors in 3D space has not been fully achieved. However, color science can measure the fingerprint of each color. Subjectivity and variety are at its minimal here.
For commercial purposes we can be aware of the meanings of colors for specific regions but again when we talk about a continent lets say Asia we have to be careful. As the world’s most populous and largest continent it includes 47 countries. I am not an authority in this matter but considering diversity of human experiences that are associated with symbols, historical and empirical events, a general conclusion seems only a sign to be aware of before we research more in details. In this case I would say ” What would be the colors to use to depict meaningful color association for a graphic design project about a summer festival in Iceland, ? or “To select colors for a home appliance to be sold in India, targeted market’s color associations, symbols, and traditions need to be identified before the consumer product can be introduced. “
Generalization is fine as long as we take the next steps to investigate this information according to our own guidelines. Another point is the generalization about the associated color’s hue, saturation and lightness. There are so many reds in the color space that some reds may be acceptable for its relative purpose even though the generalization of the red is conceived as an unsuitable color.
