Talk:Sienna

message: I don't think there's enough to be said separately about the two to warrant separate articles.  Enough of the description and images would be duplicated to make it not worth the effort.  So they should be merged, and "burnt sienna" should just be one section of this article.  --jacobolus (t) 18:45, 15 August 2007 (UTC)
thread_title:  merge from burnt sienna 

message: If I'm not mistaken, the image descriptions for burnt and raw are switched around.  I've always thought of raw as being lighter and more orangish, and burnt being darker and duller.  Erp Erpington (talk) 22:22, 26 March 2008 (UTC)
replies: text: Yes, the chart at http://www.goldenpaints.com/international/danish/products/color/conservation/msa1.php provided by User:Treedonkey with a recent correction confirms this.  Barring reasonable objection I'll relabel the top image as raw sienna and the lower one as burnt.  --CliffC (talk) 23:24, 19 November 2009 (UTC)

thread_title: I agree, the labels seem reversed

message: Perhaps this was originally added tongue-in-cheek but if every Wikipedia page had to be footnoted with obscure pop groups that once happened to mention the subject in a line of a song, then I don't think even cyber-space would be big enough. I removed this section because it just didn't seem to have any direct relevance to the subject... SkinheadEscapes (talk) 09:23, 28 April 2011 (UTC)

thread_title: File:Pigment sienna raw iconofile.jpg Nominated for speedy Deletion

message: "Sienna is a form of limonite clay most famous in the production of oil paint pigments."
Not so... the same pigments, as with just about *all* pigments used in art, are used for oil paints, watercolour paints, pastels and acrylics.  The pigments are identical, it is the binders / mediums that vary between different paint / pastel types.
This is generally known by people familiar with art, pigments and paints and the role of an encyclopaedia should be to make the knowledge more widely known.
Suggested correction:

thread_title:  Not just oil paints 

message: The color box at the top labeled as sienna has the same hex number as the web color sienna, but the RGB numbers and the numbers for HSV are quite different from those on the X11 web color list,  though im not sure why.  I think we should include the  official Web color as described on the X11 color list,  as is done in the major color articles, and check why the composition is different for the title box.

replies: text: Well, I looked at our list of web colours, and it gave hex A0522D for Sienna. I tried that on the forret.com converter and it called it "Sienna". So I've added it back in. But please check the RGB values, as I didn't. Justlettersandnumbers (talk) 22:37, 22 June 2013 (UTC)
thread_title: Sienna and web color Sienna

message: I'm concerned about some of the images that have recently been added here, and one older one. In general, I'm in favour of relevant images in articles; my concern is some of these may not be directly relevant:
* :File:Monteriggioni0001.jpg: this indeed shows some earth near Siena (though the colour may have been bumped in Photoshop). But it is not the earth that was used as a pigment, which was mined from two deposits near Arcidosso (now in the Province of Grosseto, formerly in the Republic of Siena), about 90 km from there. I suggest removing this image.
* :File:Pigment sienna burnt iconofile.jpg: this has been here for a while, but appears to show a colour quite unlike burnt sienna. I will try to upload a more realistic image in the near future.
* :File:Giorgio Vasari II - The Last Supper - Walters 371177.jpg: this is indeed a painting by Vasari, and he does indeed mention earth pigments. But without a reliable source that attests to the interpretation given by by scholars to terra gialla and terra rossa, and a reliable source that confirms that sienna pigments were used to make this particular painting, the image and caption look a bit like WP:SYNTH. I suggest either supplying those sources or removing the image.
* Pretty much the same argument applies to :File:Rembrandt van rijn-self portrait.jpg: is there a reliable source that states that this painting uses sienna colours? The reference for the general statement that he used them is a blog site, so probably not reliable (even if it is the Smithsonian); but that should be easy to replace with a better source.
You've made some very good points, and I've tried to address them.
-The image of Tuscan farmland is included to show that the earth of that region is rich in clay with limonite and haematite that are the ingredients of sienna pigment. They give it the characteristic color.   
-I've switched from the Last Supper because I don't have a citation for the composition of that picture (though it is certainly done with sienna and ochre) to one of the paintings in the Hall of the Five Hundred.  These are cited in Web Exhibits - Pigments through the Ages as an example of red ochre, or sienna. (As Web Exhibits notes, they have the same ingredient, hematite, and the same color.)  
I'm also completely perplexed by the Maerz and Paul colour; that is nothing like the artist's colour burnt sienna. Is theirs a catalogue of wall-paints, perhaps? Justlettersandnumbers (talk) 20:43, 27 June 2013 (UTC)
