Then go from yellow to orange to red if positive difference, representing a \"hot scale\".  On the flip side, a color scale from green to blue to purple for negative differences would represent a \"cold\" scale. \r\n\r\nThis would provide a color scheme so increased exposures would be \"hot\" and decreased exposures would be \"cold\"."}}
