Thank you for drawing attention to this table. If you mean �values� in the Munsell terminology then this is how it seems to me to be.elcejay wrote: Are Raven's 1929 Munsell values for Admiralty paints also in question? http://www.shipcamouflage.com/3_11.htm
We know from the archives the official reflection factor (RF) of most of the real paints.
My understanding is that the change of the Munsell scale that Raven refers to occurred in the �Renotation� of 1943.
If so, using a pre-Renotation table of Munsell value versus RF, and concentrating on the paints that might concern us on HMS Prince of Wales:
MS1 had RF 4%-6% and so should have had a Munsell value of 2.4-3 so 2.5 is in the range.
MS2 had RF 9%-10% and so should have had a Munsell value of 3.7-3.8 not 4.5 (which would give RF 14%)
MS3 had RF 20% and so should have had a Munsell value of 5.3 not 5.5 (which would give RF 22%)
MS4 had RF 32%-34% and so should have had a Munsell value of 6.5-6.6 not 6 (which would give RF 27%)
MS4a had RF 55% and so should have had a Munsell value of 8.1 not 7.5 (which would give RF 46%)
507A had RF factor of 10%-13% and so should have had a Munsell value of 3.8-4.3 not 3.5 (which would give RF 8%)
507C had RF 45% and so should have had a Munsell value of 7.5 not 7 (which would give an RF 39%)
B5 had RF 15% and so should have had a Munsell value of 4.6 not 5 (which would give an RF of 18%)
B6 had RF 30% and so should have had a Munsell value of 6.3 not 6.2 (which would give an RF of 29%)
It is the case that in the 1941-42 period there was a certain degree of variation from the official standard intended RF according to paint supplier etc. Also one assumes that judging the value was pretty subjective Mk 1 eyeball stuff by Raven and a late 1942 study at the Admiralty Laboratory Teddington of the RF of RN paints concluded that �differences of up to 9% are given for samples accepted by visual examination as a practical match�. Allowing for that the significant variances in this table from the official RF seem to me to be MS2 (too light), MS4 and MS4a (too dark), 507A (too dark, and darker than MS2 when it was the other way around), 507C (slightly too dark) and B5 (too light).
Here is the RF table I was working from so you can check my workings and indeed continue the exercise into the 1943 onwards paints where similar issues arise.

But the real issue for me is the suggestions for hue where I have a number of questions. In a few cases these can be quickly illustrated: the suggestion that B30 lies in the GY-G region of the colour circle when it was a grey blue, that B55 was a GY-G when it was a light blue and that G45 was a Y when it was a very slightly blue light grey (and indeed we know that G45 was the same colour as 507C and so should have the same notation as 507C). I wonder what he was looking at when creating these notations?
However it is the 1941 era paints that concern us here and, although I have access to the pre-1943 hue circle and this suggests some questions to me, I don�t (yet) have access to the pre-1943 Munsell colour planes so cannot take this any further for now.

Take this launch photo of Tirpitz.
Now compare it to the WEM colour coat variety. To me they look totally different and the sample here is a match to the WEM paints which I have purchased.
