Reflectance, illumination and edges (2009)
Presentation / Conference
McCann, J., Parraman, C., & Rizzi, A. (2009, November). Reflectance, illumination and edges. Paper presented at Seventeenth Color Imaging Conference: Color Science and Engineering Systems, Technologies, and Applications, Albuquerque, New Mexico

We studied color constancy using a pair of 3-D Color Mondrian displays made of two identical sets of painted wooden shapes. There are only 6-chromatic, and 5-achromatic paints applied to nearly 100 block facets. The three-dimensional nature of these... Read More about Reflectance, illumination and edges.

Does this look right? The science of colour appearance in art (2009)
Presentation / Conference
Parraman, C. (2009, June). Does this look right? The science of colour appearance in art. Presented at Science Café, Explore, Bristol

Invited lecture for Science Café given at Explore, At-Bristol, 9 June 2009. Have you considered why the swatch colour you take to the paint shop appears very different to the final painted wall? Differences between how a colour is measured and how... Read More about Does this look right? The science of colour appearance in art.

Pixel perfect - working with CMYK & RGB - A comparison of printed samples (2008)
Presentation / Conference
Parraman, C., Laidler, P., & Wang, Y. (2008, October). Pixel perfect - working with CMYK & RGB - A comparison of printed samples. Presented at 'New Ways to use Print Technology ...On Paper', University of the West of England, Bristol

This workshop compared different pre-printed samples on a range of fine art materials, which range from Japanese papers to fine art canvas. These samples demonstrate a very broad range of surface qualities and differences in the gamut of the printed...
