Hi Yevgeniy ~ The problem is that the RAL numbers weren’t around during WWI, they were introduced in 1927, if I’m not mistaken. I’m not sure if they took one colour and named it RAL-yadda-yadda or if they took the RAL-number and said “well, that looks close to the light grey of the navy, let’s make it a standard for them”.
I can only speak for the WWII Kriegsmarine where they had RAL numbers for most of their paints and when it comes to the overall paint scheme, the so-called peacetime livery, it hadn’t changed since 1896. (?)

No, not correct. RAL 3011 was the colour used for lightships (upper hull), signs (accident prevention) etc.
The colour for the antifouling below the hull was RAL 8013 which is out of production since a couple of decades. I asked the German RAL Institute a couple of years ago about RAL 8013 and if they have a sample for sale. Unfortunately not, but the closest match would be the number 040 30 30 from their RAL DESIGN product range. These numbers are CieLab values and if you run them through a converter you will then have the following RGB values: 140-65-43. I know, mixing colours upon a computer screen is not the wisest idea but it should give you at least an overall impression of this colour.
For the antifouling there was an alternative colour, a mix of RAL 3009 and 3013 but I have no idea about the mixing ratio. If you have access to Revell paints, then I would recommend their #37 which matches RAL 3009. It should be okay for a scale representation of 8013. But this is just my opinion …

The KM used RAL 7016, a pretty dark tone. The 7015 appears way too light.

No, much too light. The KM used RAL 7000 for their hulls. This colour is still in use today, the ships of the Federal German Navy are wearing this (overall). The colour has a very subtle hint of blue in it.

A few sources claim that this was an alternative colour for the RAL 7001. However, my copies of the German paint regulations (1941 and 1944) just state the 7001 (which does not mean that a shipyard used a different but somehow matching colour).

I think if we find reliable information this can be useful for all guys reading this thread and building WWI capital ships. Too late for me but I hope I am building not the last Kaiserliche Schiffe.
If you would like to add scale-effect then you probably won’t slab those ‘scale 1/1’ RAL colours on your model. You could buy those paints (e.g. WEM, Revell, Modelmaster and others) and use them as a starting point and fade them down a bit.
Happy painting ~ Olaf
