A third method, developed before scrollers, was to use three instruments, two on one side and one on the other. Three gel colors were used. The colors in the two lanterns on the one side were picked to be relatively warm and cool in relation to the single color on the other side. For instance colors of pink, blue, and lavender might be chosen. Pink is warmer than lavender and blue is cooler than lavender, so the warm side can be chosen by deciding to use either the pink or the blue lantern. This was also an advantage during the end of a scene or the curtain call on a musical production, where the greatest possible amount of light was often desired and shadows were of little interest. All three lights could be brought to full brightness, producing somewhat unnaturally flat but bright illumination.
