@mikemyers and @rrblint, for more about Temperature and Tint, check out this post:
Summary: While Color Temp adjusts the White Balance along the Blue-Amber axis and the Tint adjusts the WB along the Green-Magenta axis at “normal” temperatures, but these axes change with temperature.
You can easily verify it, if you set Temp to extreme values. The tint slider will have different effects then.
