All the Colors

This week the Lens Artists are looking for monochrome images. This most often means photos shot in black and white, but it can also mean any picture where just one color dominates. I don’t have much in my archives in black and white, but did find some monochrome images in various colors, and decided to post one in each of the four primary colors in human vision. Yes, I know, most color systems focus on three primary colors (red, green, blue), and the color receptors in the human eye also respond predominantly to one of these three hues. However, the visual system then turns this input into three opponent systems: red vs. green, blue vs. yellow, and black vs. white. This means that, at one level in human vision, there are four colors, just like in the song I used to sing with my children:

Red and yellow, green and blue,
All the colors over you.
Red as an apple, green as a tree,
Yellow as the sunshine, blue as the sea.

So here are four images, one representing each of the four colors.

ON ANOTHER NOTE: I’ve made a rather momentous decision. I will officially be switching my blog from this free WordPress location to my actual author website. From now until the end of this year I will post all my blog entries (including this one) on both locations. Starting in January 2020, though, I’ll be posting only on the website. If you enjoy my content, please start following me at my site: I value every one of my followers, and I hope to see you over there!
