Printing with tonalli: Reproducing featherwork from precolonial Mexico using structural colorants (2023)
Journal Article
Trujillo-Vazquez, A., Abedini, F., Pranovich, A., Parraman, C., & Klein, S. (2023). Printing with tonalli: Reproducing featherwork from precolonial Mexico using structural colorants. Colorants, 2(4), 632-653. https://doi.org/10.3390/colorants2040033

Two of the most significant cases of extant 16th-century featherwork from Mexico are the so-called Moctezuma’s headdress and the Ahuizotl shield. While the feathers used in these artworks exhibit lightfast colors, their assembly comprises mainly orga...

On 17 May 1861, James Clerk Maxwell delivered a lecture at the Royal Society where he demonstrated, using a lantern slide projection, his theory for colour perception in the human eye via the additive colour process known today as RGB. Three images f... Read More about The Tartan Ribbon or further experiments of - Maxwell's Disappointment / Sutton's Accident.

Moonlight (2023)
Journal Article
Klein, S., & Goodman, B. (2023). Moonlight. IMPACT Printmaking Journal,

The moon is the biggest object in the night sky. Its light has always fascinated. That special quality of light invites all kinds of superstition, from the healing power of the waning moon to good luck during full moon, from disabled children to pots... Read More about Moonlight.

Maxwell’s disappointment and Sutton’s accident (2022)
Journal Article
Klein, S., Elter, P., & Trujillo Vazquez, A. (2022). Maxwell’s disappointment and Sutton’s accident. Journal of Physics A: Mathematical and Theoretical, 55(49), Article 491002. https://doi.org/10.1088/1751-8121/aca8db

It has almost become somewhat of an urban legend or internet myth that James Clerk Maxwell created the first colour image and had demonstrated this at the Royal Institution in London in May 1861. He did present something, but what? In ‘The scientific... Read More about Maxwell’s disappointment and Sutton’s accident.

The Amber Project: A survey of methods and inks for the reproduction of the color of translucent objects (2022)
Journal Article
Trujillo-Vazquez, A., Fuller, H., Klein, S., & Parraman, C. (2022). The Amber Project: A survey of methods and inks for the reproduction of the color of translucent objects. Applied Sciences, 12(2), Article 793. https://doi.org/10.3390/app12020793

Unlike regular pigments based on selective light absorption, the so-called “effect pigments” are based on the phenomena of structural color, or selective reflectance. Structural color has appealing aesthetic qualities, such as angle-dependent hue, an...

Now you see it, now you don’t: Illusive color (2021)
Journal Article
Klein, S. (2021). Now you see it, now you don’t: Illusive color. The Californian Printmaker: The Journal Of The Californian Society Of Printmakers, 2021,

My practise is centered around color. As a scientist I can only emphasize that color is a miracle of the mind. Without the human soul, it does not exist. I am choosing the word soul and not brain, because colour is not only generated by the interacti... Read More about Now you see it, now you don’t: Illusive color.

Printing the light (2021)
Journal Article
Parraman, C., & Klein, S. (2021). Printing the light. Coloration Technology, 137(1), 86-89. https://doi.org/10.1111/cote.12523

This paper explores the relationship between additive and subtractive mixing for colour printing. Using Spectraval mica pigments (Merck)—marketed as RGB pigments—colour is generated by selective reflection and prints are based on additive colour mixi... Read More about Printing the light.

Rheological and flow birefringence studies of rod-shaped pigment nanoparticle dispersions (2020)
Journal Article

We study rheological and rheo-optical properties of suspensions of anisometric pigment particles in a non-polar fluid. Different rheological regimes from the dilute regime to an orientationally arrested gel state were characterized and compared with...

The polychromatic Woodburytype: Colour tracking in translucent, patterned gelatin/pigment films (2020)
Journal Article
Leech, D. J., Guy, W., & Klein, S. (2020). The polychromatic Woodburytype: Colour tracking in translucent, patterned gelatin/pigment films. Molecules, 25(11), Article 2468. https://doi.org/10.3390/molecules25112468

The Woodburytype is a 19th century photomechanical technique capable of producing high-quality continuous-tone prints. It uses pigment dispersed in gelatin to produce a 2.5D print, in which the effect of varying tone is produced by a variation in the...
