Turnin' up the heat: hot vs. cold colors
OK, back to color theory. The color wheel is split into two halves --warm colors and cool colors. This is not just another arbitrary grouping as it would seem at fist glance. When Isaac Newton held a prism up to the window and saw that sunlight split into seven discreet colors, he was onto something. Onto something more than introducing generations of school kids to Mr. Roy G. Biv that is.
He started a line of inquiry that ended in what we now recognise as the colors of the spectrum. Different wavelengths of mild result from special temperatures and yield the seven colorings of the spectrum. The temperature of light is measured in a scale called ranges Kelvin. Red and yellow mild burns hotter than inexperienced and blue light. These temperatures are why the colours pink thru yellow-green are stated to be heat and the colours green thru crimson-violet are stated to be cool.
Sunlight, the picture on a TV, the halogen light I'm working under are examples of projected light. My black watch, green sweater and the taupe walls of my office are examples of reflected light. The color 
So far as painting and room design go, warm colors tend to advance and cool colors tend to recede. In English, warm colors make a room feel smaller and cool colors make a room feel larger. This works indepently of the chroma of the colors used. An intensely red room will feel smaller than the same room painted in an equally saturated blue.
This warm and cold thing has given rise to all manner of pseudo-scientific hoo-hah variously referred to as the "psychology of color." Everybody's heard it at one time or another: "Purple is healing." "Red enhances your appetites." "Blue kills your appetites." "Couples fight more in a yellow kitchen." Most people hear this nonsense and buy into it uncritically, so why not run with it and start sticking pins in a doll while you're sitting in your purple "healing" room then? Unfortunately, this same malarkey gets lumped under the term "Color Theory," but don't be fooled.
The real psychology of color doesn't go a whole lot deeper than asking the query, "Do you want that color?" If a color makes you experience right, then it's a terrific shade for you. If a coloration reminds you of something ugly, then don't use it. If you hate yellow and you paint your kitchen yellow, possibilities are top that you will fight along with your partner extra. However, that conduct has not anything to do with the characteristics inherent inside the colour yellow.
There is not any magic in choosing hues however there is a lot of science beneath it. Human brains are difficult-wired to select out styles but our reactions to those patterns are determined as a whole lot through lifestyle as they may be by way of whatever else. High comparison makes a human brain pay attention and occasional contrast makes a human brain relax. If you want yellow, or you like crimson or crimson or green or blue then by using all method include what you want and paintings with it. Contrast maintains you for your toes, praise calms you down. Old wive's testimonies and superstitions should have no location in this dialogue at all. Or any discussion for that count number. The purpose here is stability and comfort. And that, my pals, is that.
