I saw the blog from the woman working on the Gauguin seat cover and felt your pain. Not only do I need the direct lighting to figure out the colors but my eyes aren’t what they use to be and I need magnification too.
There are tons of lights and magnifiers out there and all the craft stores like Michaels, A.C. Moore and Joanne Fabrics carry them.
I found the light I use at home at A.C. Moore (don’t forget to use one of their 40% off coupons when you buy it!).
I like it because it has the focused task lighting with daylight bulbs and a flexible arm magnifier and chart holder.
When I take my needlepoint with me to do away from home. I take a mini light I found online that has a magnifier that will CLIP ON to the frame of my needlepoint. See link and picture below.
