A quick exposure test, SD10 reds for what it's worth . .

I shot the card at ISO 200, bracketing from -3 to +3 in 1EV steps, here is a screen capture:

The shots above 0 were blown out and were discarded. The white balance was set from the gray patch on the card in ACR 5.4 and opened in PSE6 from which the screen capture was done. Each exposure was adjusted in ACR to make the histograms similar. The under-exposed red at the top looks quite familiar. That red has no blue in it, so something got clipped somehow. RGB equaled 195, 70, 0. Hue and Sat were 22 deg, 100%, obviously wrong.

Perhaps the OP should measure his orange-colored reds' RGB values (not with a screen picker) and deduce something from that?
