RED COLOR

The meanings of red and people's reactions to it tend to be fairly consistent across all age groups and cultures. Psychologists and researchers agree that Red is a color which stirs up passion, with both negative and positive color meanings. We think of Red as the color of both Cupid and the Devil. It's the color associated with both Love and War.
Pure Red is the hottest of all the Primary Colors. It's the most visually stimulating, most intense color on the Basic Color Wheel.
In fact, Red is so intense that people suffering from temporary blindness due to a brain injury will begin to perceive red long before they see any other colors.
Women seem to be more attracted to cool Reds which lean toward Violet. This range of preferences spans all the way from Cherry Red toward Magenta and Fuschia. When lots of white is added to these Reds to create Cool Pastel Pinks, the meanings of red changes dramatically. The subconscious and conscious reactions shift toward the soft and ultra-feminine the paler the tint becomes.
Men, on the other hand, generally prefer warm Reds which lean toward Orange.This range of preference begins somewhere near Tomato Red and goes all the way toward Indian Red and Brick. When Black or Grey is added to create Warm Shades and Tones, the resulting Reddish Browns are very earthy and masculine.
In my paint swatches above you can see how Red, a Primary Color can be varied by adding more Violet or more Orange. Each one of these swatches still belongs to the Red Hue family even though they've been mixed. The meanings of red can change quite dramatically depending on how intense or how light it is.
Notice also that mixing in more Orange makes the Red lighter. More Violet makes the Red darker. That's before mixing in any white, grey or black to tone down the brightness.
When choosing color schemes be careful about how much Red you use. A little can go a long way. It makes such a bold statement at full strength. The meanings of red are so strongly ingrained that you're wise to limit its use as an accent color. Or you can lower it's intensity with other colors.
