You are always so damn quick and final with your judgments! But your judgments are mostly based on theoretical considerations and ignore other aspects.
And your judgments are not based at all on theory or on facts. You catch pictures on the Internet, see a signature there written by some illiterate amateur, and then post it under the guise of truth, misleading people.
A man of Potemkin's rank could wear what he pleased! And he did!
At home, in his bedroom, he could really wear anything. But at the court or troops, he could only put on a uniform that was due to him according to his position or rank. Let's take a look at all the options you suggested. Well, to make sure that during that period he could only wear pale-yellow, white or green.
As is well known, there are many pictures of Prince Potemkin-Tavritchevsky - and they show him in many different uniforms!
Do not forget that because of the orders and sewing on the uniform at the bust, our time frame is narrowed to the period 1784-1788.
Here in white...:
We look at the portrait, we see that he is in white, we read what I wrote in my previous messages, where I did not deny the white uniform, but ... I correlated this with the cuirassier uniform, which is often depicted on reproductions white, but not pale. Now look at the orders - there is a ribbon of the Order of St. George 1st class, which Potemkin received in 1788, which is not suitable for this bust. The white uniform is nothing more than an incorrectly depicted admiral's uniform. The portrait itself, shown by you here, is the work of the contemporary artist Vasily Nesterenko, probably created based on the portrait of Potemkin by Johann Lampi, written in 1791, which again does not fit the time for the bust.
Here in red...:
(Original-piece)...:
Are you deliberately twisting the facts? There are completely different costumes on the fragment of the portrait and on the photo of the uniform. Only the blind will not see the difference. I will say even more that a fragment of the portrait is not Potemkin !! This is a portrait of Alexei Dmitrievich Lansky by D.G. Levitsky. in 1782. The red suit from the museum is generally a civilian dress. Circled in red in the photo is "dignitary's suit, 1760s." and "Ekaterinin's nobles were dressed in such red uniforms - namely, the landowners of central Russia." The landowner is not even a civil servant!
And here in blue...:
To begin with, I’ll say that in this portrait it’s not clear whether it’s blue or green - it looks different in different photos. The man depicted is already aged, but at the same time he clearly lacks the Potemkin orders, besides, what kind of uniform is he wearing? I'm at a loss to determine, moreover, it looks too much like a modern style of painting. As a result, I can say that this is really modern painting, namely the painting "Prince G.A. Potemkin-Tauride" - the author A.I. Fedorov (1993)
Do you know how many such portraits with colorful uniforms? I don't know, but I found at least a couple of dozen images of different colors, painted between the end of the 18th century and up to the present day. The colored original is unknown, while all of these colored ones were redrawn from a 1789 engraving by James Walker, and some from later pictorial copies of this engraving.
Here's the uniform you're talking about - it's preserved and it's actually dark green...:
It is not as dark as it might seem initially, for museum things it depends very much on the lighting in which the photo was taken (see my photo, the same uniform is lighter there). The photo shows not Potemkin's uniform, but the uniform of an infantry lieutenant general until 1786, at that time (remember that the bust is for 1784-1788) Potemkin was a general-field-marshal, and could not wear such uniforms.
Just compare what officer uniforms look like in photos from museums under different lighting conditions and different levels of color correction of photo reproductions, and this despite the fact that in reality they are almost the same color.
Here you have bluish, and green, and yellow-green, and khaki.
However, the bust that Pierre is painting was made from a specific template - and on this template its undoubtfully BLUE...:
And IF Pierre works according to a specific template, then I think it's absolutely right that he also sticks to the colors!
From this point of view, green (because of the original uniform) is correct, as is blue (the painting)
I already wrote above that every artist is free to do as they wish, I only give information about how it was according to available sources.
