Bacchus and Ariadne
I cannot stress enough that using an image that completely misrepresents the subject of the article (in this case the colour ultramarine) is worse than using no image at all.
There was a Sesame Street song, when my kids were little, that went "One of these things just doesn't belong here. One of these things is not the same!" Of the four images in the gallery, three represented the colour ultramarine correctly, and the fourth was glaringly different. The reason was either that the colour reproduction was poor, or the colour wasn't actually ultramarine at all. If a written source says that it is ultramarine then it up to the creator of the gallery to make sure that the colour reproduction doesn't misrepresent the subject of the article. The thing that was going to tellyou that it was horribly wrong was your own observation. I cannot stress enough that editors need to look critically at every image that they choose to illustrate their subject. Amandajm (talk) 06:11, 8 July 2014 (UTC)
I split and moved a section to Ultramarine#Artist's ultramarine shades
It's not clear if these shades are actually "ultramarinee" as described in the rest of the article - ie a specific pigment. Specifically its not clear what the actual definition of "electric ultramarine blue" is - the reference , quote "The color displayed in the color box above matches the color called ultramarine in the 1930 book by Maerz and Paul " suggests that the content in the article is derivative, ie not encyclopedic. The "International Klein Blue (IKB)" is already noted elswhere in the text
As such I will remove that part to his talk page for now. Below

- Maerz and Paul A Dictionary of Color New York:1930--McGraw Hill Color Sample of Ultramarine: Page 105 Plate 41 Color Sample F12 Ultramarine is shown as being one of the colors on the bottom of the plate representing the most highly saturated colors between blue and violet (the colors on the right of the plate represent the most highly saturated colors between violet and rose); ultramarine is shown as being situated at a position exactly one-half of the way between blue and violet.
The issue is that the info given is derived out of context from a book into a RGB value - I don't have access to the book so I can't add anymore. I don't think it actually is relavent to this article. Maybe another one on blue colors but I am not sure if it is encyclopedic. Prof.Haddock (talk) 16:05, 12 July 2014 (UTC)
