Re: Questions about Mixing USN WWII Camo Colors

I don't have a lot of time for this right now, but a couple of points. If you really want to do what you're doing you're going to need to know chemistry and trawl my Camouflage section a bit more. They actually changed formulas a couple of times. Additionally, my take on this (I.e. John, Randy, etc., can come in and slap me if I'm wrong) is that the deck paints (20-whatever) were a different formula than the bulkhead paints (5-whatever) but were largely matched - for example the early-war flight deck stain for carriers was to be matched to 20-B, so 20-B and 5-N should be fairly close. I don't have my Snyder & Short / shipcamouflage paint chips with me, but they are essential if you're wanting to mix matches.

Questions about Mixing USN WWII Camo Colors

Hey guys, given the fact that the only accurate colors available anymore are WEMs I've decided to mix up some batches of my own colors. Don't get me wrong, WEMs paints are excellent, but they're enamels and I can't work with them anymore. I'm switching entirely to acrylics so the options are quite limited. MM and PS discontinued their lines, God only knows why, which leaves Life Color's line of inaccurately matched colors only sold in sets. Why can't somebody make accurate acrylic colors anymore?

So anyway, I read through several Ships-2 reports and found the mixing instructions for 5-N, 5-O, 5-H, and 5-B. I'm still looking for 20-B. It says it was to be issued premixed but I can't find out how its mixed. Anyone know the missing recipes?

They call for the Blue (5-BTM) or Blue-Black Tinting Material (5-TMa) to be added in different proportions to the untinted White Base (5-Ua). My plan is to buy several jars of MM Flat White acrylic and an appropriate Blue-Black and Blue and mix my own jars. I'm going for the early-mid war "purple-blue" colors, not the late war neutral grays.

Here's the mixing instructions I found.

http://www.shipcamouflage.com/ships2_3_ ... paints.htm

Based on the above numbers, I've worked out the math and arrived at the following ratios for some of the colors:

5-N = 3/8
5-O = 1/8
5-H = 1/20
5-B = 1/40
5-P = 1/160
5-L = 1/40

If I were to mix 1/2 oz. bottles (standard MM/PS size) then I would add the following to a bottle of white to obtain each color:

5-N = 3/16 oz or 5.545 ml
5-O = 1/16 oz or 1.848 ml
5-H = 1/40 oz or 0.739 ml
5-B = 1/80 oz or 0.370 ml
5-P = 1/320 oz or 0.092 ml
5-L = 1/80 oz or 0.370 ml

I have a small syringe marked off in hundredths of a milliliter so measuring them out will be easy.


I came across this memo describing the makeup of 5-Ua and 5-TMa.
http://www.researcheratlarge.com/Ships/ ... aints.html

Does anyone have any color chips or know where I could find them (along with 5-BTM) so I could start with an accurate base for mixing? I have chips of the final colors but can only guess at the tinting materials. If I read it correctly, 5-Ua is a pure white (cool), and 5-TMa is Ultramarine Blue (a bright, pure blue; cool) mixed with pure black. Would I be correct in surmising that 5-BTM would be the same minus the black?

Unless I can get some more info I was planning on using MM Insignia Blue as a starting point for 5-BTM and with some added black for 5-TMa.

At the end of the Ship-2 from June 1942 it says it supposed to contain paint samples of the tinting materials. Anyone ever come across those or know of approximate matches to them?

Also, what about the tropical greens? I've read they use a new green tint base called 5-GTM but I can't find out how its mixed. I have no clue at all how the browns were mixed. Anyone?

I've been all over this site: http://www.paint4models.com/ but their matches for the USN colors are all neutral grays or way off.

I'm not going to scrutinize these down the fraction of the drop but I want them to be as accurate as possible. Any ideas guys?

Any and all help is appreciated as always,
-Mike
