Color is important to a physical description, but here’s a few suggestions that go beyond Roy G. Biv to provide for a particular hue with a single word.
One of my on-going word collections is of colors. I love to stop in the paint section of a hardware store and find new names for red or white or yellow. Having a variety of color names at my fingertips helps me to create specificity in my writing. I can paint a more evocative image in my reader’s mind if I describe a character’s hair as the color of rust or carrot-squash, rather than red.
So for fun, I created this color thesaurus for your reference. Of course, there are plenty more color names in the world, so, this is just to get you started.
