Here is a John Isaac shot of Adobe's Russell Brown being attacked by a roll of killer toilet paper. Figure 6-28 If we examine the roll of toilet paper closely with Lightroom's color sampler, we see it contains a lot of blue. (Place your cursor over the area you wish to measure. A RGB percentage readout will appear in the toolbar.) This blue cast is a result of the blue sky reflecting back to us via the white wrapping. (Color shifts like this are common in snow shots as well. Snow, while really white, can appear very blue because of the reflected sky.)
