Buren's colour choices are determined by the fact that these are the only colours the film comes in, and the order of his colours is dependent on the alphabetical order of their names.
To make a crude analogy, two bracelets, each consisting of five red and five green beads, could be arranged in many different isomeric forms, depending on the order of the colours.
Once again the order of the colours was the same for everyone, so maybe it was the repainting of the cell that made a difference, rather than its pinkness.
Behaviourally, the reaction time effects we obtained for synaesthetic priming were of the same order of magnitude (colour: 56 ms, synaesthesia: 79 ms) as previously established colour priming effects in the same subjects (van Leeuwen, Petersson, Langner, Rijpkema, and Hagoort, submitted).
Meanwhile, Farmanfarmaian continued to work, exploring the inherent geometric order of pattern, colour, and reflection.
Secondly, this selection policy increases the security of the PEC-based steganographic scheme because it is sensitive to the orders of the colours in the colour table.
By randomising the orders of the colours of the colour table in Step 1 of the PEC algorithm according to secret key, we can ensure the security of the proposed scheme.
The order list of colour shows how, by selecting a node, the next relay node could travel toward the sink.
With a different colour table, the PEC algorithm will produce a greatly different clustering configuration and wrong ordering of the colours within each cluster, which will prevent the hidden data being extracted by the attacker. .
Although the codes do not follow exactly the same pattern, the ordering of the colours by hue is similar in both the Flinders and Sibthorp numbering systems, but is markedly different in the unattributed painted colour chart form Madrid. Prior to this study it was unknown whether the pigments in the Madrid chart correlated with those found in later paintings [1 3].
