Massachusetts Coastal GP7U 2006 was originally Santa Fe Railway GP7 2689.
On our visit to Cape Cod, we found this antique from 1951 basking in the late afternoon sun at the Hyannis yard.
I made a selection of photos from different angles, using different cameras and different lenses, to show how the angle of the sun and other differences can greatly affect how color is perceived and recorded.
So which is the ‘true’ color of the locomotive? There isn’t any ‘true’ color, it all depends on how you perceive it in the moment. The appearance of paint color changes with as the light changes.
Cape Cod Central’s cranberry is a difficult color in part because it is a mix a blue and red hues. Blue is greatly affected by the color of the sky; red by the sun. With a polarized sky and the sun low on the horizon the angle of view (and angle of reflection) affects the apparent color more than on a day with more diffused sunlight and the sun higher in the sky.
Complicating matters for the modern day photographer is that different camera sensors and color profiles also affect the way that color is recorded.
