Xan Gregg has done a data quality analysis of the Wikipedia colour data I used in recent posts (here). Unsurprisingly, the data is not great quality. The outliers discussed are not included in my analysis, but the colour conversions are not totally consistent either. As Gregg points out, Wikipedia is hardly a good source for Visual Psychophysics research, but it's still an interesting proof-of-concept.
