About the Colour Temperature Editor
Warming adds red and removes blue; cooling does the reverse. This is the correction for photographs taken under tungsten light that came out orange, or in shade that came out blue.
Temperature is one of the two white-balance axes. If a cast is green or magenta rather than orange or blue, the tint control is what fixes it.
