"He who marches out of step hears another drum." ~ Ken Kesey
In the past, when cross checking dye lots, I have built viewing boxes painted neutral gray and includind up to three light sources....daylight, incandescent, store lighting etc. I wired that we could view colors under any possible combination. Certain colors particularly pinks and purples are metameric, meaning they will shift depending the light source the substrate is viewed under. For a quick overview of lighting sources, measurement, and color accuracy you can check Pantones website or believe it or not, your Grainger catalog has information on all this. Pantone also sells viewing boxes for a ridiculous amount of money for us tee shirt guys.

What's a cheap AND easy solution?Good Morning Pierre.......Grainger and a Saturday with some power tools, a friend or two, and a pizza!pierre
Thats right Erin........for Nike each season we would get a "kit" with printed samples, films. BOMs, and color chips to match. Often these would be pieces of sneaker , shoelace, or other material. Part of the approval process is to match these colors on two inch circles under those lighting conditions. There were always two formulas......one for a white shirt one for a white underbase.
I came from offset printing (design side). I never really understand the light box for viewing colors. So you make this box so that the colors are 100% true in the box. The press guy takes a printed sample under the light box to compare the print to the pantone colors. I don't see the reason to have a true color box for comparing colors. The light your under will affect both colors the same. You just have to adjust the colors to make them look the same. No reason to have a true color light box. I understand it may be easier to adjust colors but not needed. I was once told to use full spectrum lighting. They are the Daylight bulbs you can find everywhere now.
