Talk:Cerulean

Merge discussion
This overlaps a lot with cerulean blue, but technically cerulean blue is a pigment with a specific shade, while "cerulean" is a broader term for sky color (according to OED). So I can't make up my mind whether we should merge the two, and if so, under which name. Stan 16:04, 17 Nov 2004 (UTC)


 * I guess you'd be best putting the narrower term under the broader one if you're merging the two. - Jimp 24May05

Cerulean is also the name of a city in the English translation of the original Pokemon games. is the above piece of information notable? --Melaen 00:32, 30 July 2005 (UTC)

Merge request
Cerulean blue should be merged into here, and the article should focus on the pigment, not the "color". It can be mentioned that "cerulean" is also used as a name for blue-green colors, but the pigment is the encyclopedic part. --jacobolus (t) 21:33, 20 September 2007 (UTC)


 * I'm not sure I agree with this decision. A pigment and a color are distinct things.  For example, for black (the color) we have several pigments: bone black, lamp black and etc.; and also dyes. Should everything in the world that happens to be "one color" be listed on the same page?
 * Some time back, this had been discussed and the conclusion was to leave them separate, because other reference sources seemed to distinguish the two. Cerulean as a color is not one color; it is a range from cyan to pure blue (desatuated).  The whole point of the pigment as a distinctive item was its pure "blue" character, when other pigments in that day and age all had greenish characters. CoyneT talk 02:06, 2 November 2007 (UTC)

Different colour specifications?
I know that the conversion between colour spaces is a very tricky issue, but this page lists two different shades of Cerulean blue, which are different again from the value for Cerulean blue published by Pantone.

I suggest (based upon WP:V) that Pantone's definition should replace the other two. Randomgurn (talk) 08:17, 2 July 2009 (UTC)

The two shades of cerulean you erased are the actual colors of the cerulean pigment and the cerulean blue pigment. I restored them with sources and put the Pantone color, which is much paler than the color normally called cerulean, at the end of the article. Keraunos (talk) 15:00, 4 July 2009 (UTC)

Whilst I would dispute your claim that specific RGB (emissive) values uniquely correspond to absorptive colours (my monitor isn't your monitor, what was the camera's white balance setting, etc), it's OK that you changed the colours back; however, they were previously unsourced, and thus not verifiable.

Examples of color
The first sentence of this article gives a range of color shades. It would be helpful to me to see an example or set of examples, ranging from the one to the other.Anonnymos (talk) 20:54, 14 February 2014 (UTC)

Use in artistic painting
Methinks that the section "Use in artistic painting" needs at least a picture of the real (in this case: oil) paint with genuine PB35, not "just" of a hue of cerulean. Does nobody have the genuine PB35 (oil) paint to make a photo and upload (yes this paint is expensive I know), perhaps even in comparison with a couple of other colours like ultramarine (PB29) and phtalo blues (PB15) for comparison's sake?

 * Done.--MWAK (talk) 21:48, 19 November 2016 (UTC)

Inconsistency: Date of First Use
In one place it is asserted that the first mention of cerulean as a color was in 1590; in another case it is asserted to have been 1859. Or is the distinction between "cerulean" and "cerulean blue"? Xenophonix (talk) 20:29, 6 May 2015 (UTC)


 * Probably indeed the last was meant. The 1859 mention was really about a pigment, not so much a hue.--MWAK (talk) 06:30, 15 April 2018 (UTC)

I would have to say, as an artist, it was confusing to show the first use in the English language being 1590, and then later saying that the pigment was not even discovered until the 18th Century, and only designated as such in the 19th Century.

Possible removal from list
An entry in List of colors: A–F contained a link to this page.

The entry is :


 * Dark cerulean

An entry in List of colors: N–Z contained a link to this page.

The entry is :


 * Vivid cerulean

I don't see any evidence that this color is discussed in this article and plan to delete it from the list per this discussion: Talk:List_of_colors

If someone decides that this color should have a section in this article and it is added, I would appreciate a ping.-- S Philbrick (Talk)  18:21, 11 September 2018 (UTC)
