Tono & Lims - Star Light Series: Regulus

Got this because it’s blue, fluorescent, yet dark enough to be generally useful, how could I refuse? It also changes color on different paper. On Iroful it starts blue, then goes teal, then dries more blue. On other paper it’s more blue.

Under UV it glows blue, except on Iroful where it’s more green again. On other paper where there’s more ink, it’s more green.

Don’t mind the messy dip pen writing.

Scans

Scans are reasonably true to color and show the differences in hue between paper types. Col-o-ring is much more blue, Iroful more teal, MD is in between.

Photos

There is a stark contrast between the glow on Iroful and MD. Iroful is bright green, while MD is blue except in the very heavy areas of the swatch.

These photos show each swatch under visible light, a mix of visible and UV light, and UV light alone.

Col-o-ring paper is very reactive to UV and the paper itself glows blue brightly, which makes the glow of the ink appear less intense. Iroful is mildly reactive to UV and glows a little. MD reacts very low so it shows off the glow of the ink the best.

A mix of UV and visible light seems to yield the best results to the eye.

Microscope

As with the scans and photos the color differences between the paper are very apparent.

Microscope UV

These photos show magnified portions of each swatch under visible light, a mix of visible and UV light, and UV light alone.

Microscope UV photos are a bit tricky since I have to dial the light up/down on the microscope and add UV light from a flashlight. As the UV light intensifies, it seems to play tricks with the microscope’s camera with the background to some extent.
