Why does colour psychology make so much difference to us?

In 2013, two Australian academics set out to discover the answer to a deceptively simple question. Why is there such a thing as colour psychology, but not shape, line or texture psychology?

For this reason, there are no proportion-shape-line-texture prediction agencies, and chromotherapy is not challenged by proportion-shape-line-texture therapies. Colour remains special and, given its rich and complex heritage, is likely to remain so.” More →
