RGB range for cold and warm colors?

Question

What are ranges of cold and warm colors (http://www.diy-bathroom-remodel.com/images/color_wheel.gif) in RGB?

Answer 1

Looks to me like

if (B>R) { 
    color=cool
} else { 
    color=warm
}

is a pretty good approximation. You can check this out on your color wheel using: http://www.colorzilla.com/firefox/
