Bring Color to FA. It looks really good so far, maybe some improvements and a peer review are in order?
Decide on a list of "major" colors and work on those articles. Organize "minor" colors into the main articles.
Update infobox: normalize numbers, decide on which spaces to use (RGB, CMYK, etc.), add caveat about monitor differences, change swatches per talk page.
Initial strategy is to sweep through list of colors: for each entry, I shall normalise the values and ensure that the entries in the table correspond to the appropriate article. (from previous listing - older, but worth keeping)
