Leave it to the Office Supply Geek to experiment and find out for us this heretofore arcane wonder:

“I tried the Noodler’s Blue Ghost on multiple different papers and it seems to get the best results when used on non-white paper, especially a non bright AND non white paper. The Rhodia Web Notebook with 90g paper in the cream color got by far the best results. The photo above shows the writing sample in that Rhodia Webnotebook . The light that I used for getting these pictures is from Feit Electric, which is a compact fluorescent light, so its even environmentally friendly. There are many better and worse options for a fluorescent light, so do your research and find the one that is best for you, but also be aware that lights like this can be dangerous for your eyes, so exercise care when using them….”
