Starting from the 424 color specimens of the OSA-UCS set, we propose a fuzzy partitioning of the color space.
Another benefit of the system and probe presented in this work is its ability to image color specimens.
The Dupli-color specimen shows the most irregular deposit after ageing.
By Elisabeth Biondi January 13 , 2011Whenever I'm on trip or at a museum, I look for postcards to take home: not the standard color tourist specimen, but the black-and-white beauties or the quirky, funny ones.

Then, 12.5 mg of β-Naphthyl acid phosphate and 12.5 mg of O-Dianisidine tetrazotized (Sigma Corporation) were added to color the specimens.
The flour of pumice used for the removal of existing extrinsic stain (to determine the inherent color of the specimen), does impart a quantifiable polish to the specimen surface and it is similar to the prophylaxis paste used for dental cleanings in the dental office.
The number of puncture attempts was decided by the quantity and color of the specimen obtained.
Two-sample t test was performed to investigate the effect of a PAS mordant versus no mordant on overall color difference between specimens exposed to light and laundering.
In contrast, the dislocation loops in the machined specimen colored with the atomic potential energy, as shown in Figure 6 (b1), are with lower potential energy than those in the pristine single-crystal copper specimen, as shown in Figure 6 (b2).
Two-sample t test was performed to investigate the effect of a PAS mordant versus no mordant on overall color difference between specimens exposed to light and laundering, where the overall color difference Δ E was calculated by: Δ E = (sqrt {(L_{1} - L_{2} )^{2} + (a_{1} - a_{2} )^{2} + (b_{1} - b_{2} )^{2} }).
