I notice in the New Items topics some discussion about the colour of pre-1938 grey used by the DRG for their electric locomotives.

So was ist Richtig?
What is right?

I have 3 DRG electric locomotives that qualify for examination of this intriguing question.
To start the ball rolling here some photographs.
1. Märklin 3187, E32


2. Märklin 37681, E18


3. Märklin 37196, E91 - Märklin 37681, E18 - Märklin 3187, E32 - comparison


4. Märklin 37196, E91 with Märklin 3187, E32 comparison


5. This last photo in comparison shows how difficult it is to use photography as evidence for colour.
The grey on 37196 looks completely different to the previous photos.

Another subtle point is that sometimes the promotional images of the grey E91 looks more like the E32 colour.
Let's not forget that the 3187 is also from the former 'Hobby' range.

Over the years, I've realised that manufacturers do the best that they can with the available information.

I've used AI colourisers to process DRG coach photos and they mostly come out on the 'brownish' side of the colour that we know as 'brownish-green'.

Should we now move onto interpretations of CIWL 'Teak' shades, as interpreted by MRR makers?
Some of those AIed photos suggest that the darker version is actually what the smoke-stained exteriors might look like.

At the end of the day it's 100 years ago and the records that we have have survived two world wars. Meh.
