As it looks like a colourised photo I would not rely on it for accuracy in colour choice.
Surprisingly it looks like it isn’t colourised: https://www.akg-images.fr/CS.aspx?VP3=SearchResult&VBID=2UMESQ54B4WHZ5#/SearchResult&VBID=2UMESQ54B4WHZ5&POPUPPN=15&POPUPIID=2UMDHUW6J6J6
Yes, I've changed my mind having seen the others from the series. However, as I demonstrated, there's been some (presumably) digital changes made in some versions of the images, in saturation, highlighting and shading.
The picture is not colourised, its Agfa transparency if I remember correctly and one of a series.
