Painting and Fluorescent lighting

The shelves have all been painted, and all but one section brought from the basement to the second floor. I have found that fluorescent lighting has an effect on colors. If you have two shades of one color that lighting may not let the difference be known. Down in the basement the shelves looked great, upstairs in the real world, it turns out the small section was painted in the lighter gray but was touched up near the top with the darker. Downstairs it looked like the same color, not so with incandescent lighting.
