Beth: I see our house with a light olive green body, bright white trim, and dark red shutters.
The fact is that men and women may really see color differently. About 50% of women are tetrachromatic which means they have four types of cone receptors instead of three. Cone receptors are cells located in the retina that are responsible for our both our vision of color and the detail in which we see it. Just having more or less cone receptors isn't the whole story. It turns out that even with people with the same number of cone receptors the interpretation of color can vary greatly. Human beings have a color experience which means that we relate to color as it relates to experiences in the world because our brain does an automatic color correction so things appear "right" to us despite wearing sunglasses, colored lenses, or colored lighting. So my brain interprets color differently from Steve's brain. (Clearly my brain's interpretation is the correct interpretation therefore my color choices are superior, right?)
It's more than just a physical difference. Men and women perceive colors different as part of our different gender experiences. If we go back to our original hunter/gatherer roots women evolved to prefer colors on the red spectrum as berries, fruits, flowering plants, and other necessary foods come in that color. Also, as the primary caretaker of children since time began, women had to perceive variations of red as an indication of fever or rash in our children. Being attune to the red spectrum may have been necessary to save a child's life. Men evolved to look for colors on the blue spectrum: blue sky indicating good weather necessary for hunting, blue water indicating good watering hole where animals may be found. Purple clouds indicating a storm coming. Movement in the shadows indicating attack by an enemy or animal. Seeing variation in the blue spectrum may have meant life or death to the man his tribe.
Well, Steve and I are already ahead of our biology: we both want a green house, it's the depth of color that has us at odds. I always prefer light colors and Steve always prefers darker colors. This doesn't appear to be biological as much as personality preference.
There is one big factor that must be considered that is probably more important than biology, personality, evolution, or societal influence: I am the one who is actually doing the painting!
Light olive green, welcome to the neighborhood!
