Sensor Warning-Lighting is not created equal

[Jason Rudolph]

IF this turns out to be a big issue, you will need to be careful calibrating at the event. Usually, the pits are lit by venue lighting, normally HID, which has much more blue in it. However, the field is normally lit with theatrical lighting, which is a tungsten source, and has much more red in it. I do not think this will be much of an issue though, as you are looking for the three primary colors (plus yellow). The camera should be able to discern between these colors, even if the calibration is off by a little.
