Vision

Cones and rods.

• Rods: light, not color. 
• Cones: color; three types of cones:
• L-cones, long wave: longer red wavelengths
• M-cones, medium wave: yellow- to green-medium wavelengths
• S-cones, short wave: blue short wavelength

Some biologists shorten this to:

• three types of cones:
• red
• yellow (golden)
  
• purple

Yellow and purple are complementary colors.

Complementary colors are pairs of colors which, when combined or mixed, cancel each other out (lose hue) by producing a grayscale color like white or black. When placed next to each other, they create the strongest contrast for those two colors. Complementary colors may also be called "opposite colors."

The book I am reading this week:

• Braiding Sweetgrass: Indigenous Wisdom, Scientific Knowledge, and the Teaching of Plants, Robin Wall Kimmerer, c. 2013.

In the chapter I just completed, the author spoke of 

I was curious about something she wrote. In the process of looking that up, I came across this in northerngardner. Note the source. Whoo-hoo!

One of the more striking / beautiful landscape paintings / photographs are those of canyons taken at dusk. One wonders if the yellow / golden setting sun accentuates the purple formations along the canyon wall.

More on yellow / purple contrast here.

As I tell the granddaughters: never quit reading.
