My work was shown in the Radiant Gallery, Plymouth as part of the DataAche Conference, the 21st International Conference on Digital Research in the Humanities and Arts.
I presented a colour reference book which features 1137 Pantone Colours printed across 5 substrates (paper, wool, linen, cotton and silk) to compare the visual differences. Each colour featured a table of metrics listing the numeric values needed to create it digitally (RGB, HSB, LAB, CMYK and Hex). 4 printed colour charts (wool, linen, cotton and silk) were hung on the wall so that visitors could get a closer look at the differences between the substrates. I wanted to demonstrate that the substrate being printed upon played a big part in colour result.
After making the colour reference book I used a spectrophotometer to measure each coloured swatch in the book. The values returned were translated back into digital colour, using LAB values, and converted into HSB data in order to compare the hue, saturation and brightness shifts between the original screen colour chosen and resulting printed colour. To visualise the shifts I created colour maps using hue, saturation and brightness circles with the screen colour plotted centrally and the resulting colours placed on the outer rings to demonstrate where hues were shifting, and how the intensity and lightness of colours changed. I proceeded to take an average of each colour shift to create a predicted colour change which was plotted on a second map so that each hue had two maps to show actual shift and predicted shift. These maps were printed onto matt textured paper and displayed on the wall alongside the reference book and colour charts.
Its all work in progress for the moment, the next step is to test if the predicted colours are a better match than current software gamut mapping previews.
The group exhibition featured work by other 3D3 students on the theme that we are drowning in data and the use and misuse of data.
