Difference between 赤｛あか｝ and 赤色｛あかいろ｝


What is the difference between 赤｛あか} and 赤色｛あかいろ｝？




赤色 is just a redundant form of 赤

赤 also has other meanings besides just red, so 赤色 can be used to clarify
you're talking about the color red in a confusing situation.

An example in English would be:

> the curtains are red

versus

> the curtains are of red color
