I got quite a few responses on my question about using color in fiction. Black and Red, or as Erik said, "Noir" and "Rouge," were popular colors. I was a bit surprised to see that gray was quite popular, although it makes sense after discussions by H.E. and Wayne. By the way, gray and grey are two different colors to me, or at least different shades. I use grey, with an "e" for the darker shades, where there's more black than white in the mix, and gray with an "a" for when there is more white than black.
Kate S admitted that pink was not uncommon in her romance work, so maybe there's some truth to that old saw, but Sheila posted about how she uses shades of light as descriptors. That might be another item worthy of consideration. Stewart mentioned color as an element of theme, and described Bradbury's excellent use of that technique, and Sid brought up weather as a plot element and descriptor. All in all, a very nice discussion, and I may particularly want to explore the idea of light as a descriptor and of weather in plot a bit more. But now I think it's lunch time. I'm gonna have something...red.
