Iris Close-up - the effect of white balance

Decided to do some close-up work this morning with an iris (indoors).  The flower was lit with two simple reflector based workman's lamps each with a 60 W incandescent bulb.  The first setup was created with auto white balance fooling the camera a bit to consider a cloudy situation thereby enhancing the warm tones.This next image is with a slightly different composition and crop created after doing a custom white balance to have color accuracy despite the mixed light.   Both images were photographed using the identical background.
