Thanks Brooke--I didn't try any specific color luminance/saturation, just the overall saturation slider in PS Camera Raw. Will try to manipulate just red/orange/yellow to see what happens!
Incidentally, here is a characteristic spectral curve for Si detector response (click the technical images tab):
Silicon Detectors - Edmund Optics
I haven't yet found a curve for Si detectors that mimics the exposure curves I'm used to seeing for film (although I've seen them in the past). If I recall correctly, it is fairly linear except there is a shoulder which usually translates as blooming in the high end of the dynamic range.
