For future reference I'd like to remind you all two simple tricks:
1. Suppose you got a picture in your email and suspect that its colors are not true. Having a picture in which one spot is known for sure to be white allows for fairly accurate reading / managing of any other color in that picture.
Just open your picture in Photoshop, then go Image>Adjust>Levels. In that last wizard pick the eye dropper from the right (highlights) and, after sampling on your picture's white spot, the image automatically redefines itself accordingly to what was pointed as being white (high light) in that picture. Somewhat related to this topic is the next trick.
2. Most digital cameras today have manual controls and so many bells that only a few really know how to take advantage of. As result most pictures are far from perfect when it comes to color accuracy. The true remedy is called white balance.
Before taking a picture find or give yourself a white spot within that frame. If there is no pure white color in that frame composition you need to temporally bring one in it, say a piece of white paper. Then, instead of risking a picture using one of sunny, cloudy, fluorescent or incandescent light adjustments readily available (usually there is more than one type of light source in any given environment and that makes accurate photographic color rendition a very difficult job) go to the next setting (which symbol looks like 2 little triangles with a circle in between) and push on Set button while keeping camera aimed at the white spot. After a few seconds your camera’s color palette is readjusted and the picture’s colors will look perfect. This is called white balance adjustment and in this last setting you actually ask your camera to define the white spot / paper in your composition as such and read any other color in that composition accordingly. Evidently, when light conditions change white balance adjustment should be performed anew.
