Variation in colour with different "Daylight" lamps

These charts were shot as part of an HDR experiment, they looked pretty much the same to the eye but to camera...

I've trimmed the shot to remove some of the surrounding, and irellevant, information.

Shot on an Alexa. This is a composite made form one shot, I have just trimmed excess space between the charts.
