franky boy Posted March 4, 2022 Share Posted March 4, 2022 Hello chaps Just a quick question on US Interior Green for WW2 a/c. Is Humbrol 226 a decent match? Thanks James Link to comment Share on other sites More sharing options...
treker_ed Posted March 4, 2022 Share Posted March 4, 2022 (Oooh looks what's just been opened.....) In all seriousness though, It's one of those questions on colour that has a whole heap of answers! The sort of question on quiz shows "We asked 100 people..." you'll get 100 answers. I've just done a quick search on the forums using the search term "Interior Green" and there were 84 pages of return, refined to US Interior green, and a more manageable 5 pages came up :- (copy and paste this into your browser) https://www.britmodeller.com/forums/index.php?/search/&q="US interior green"&quick=1&type=forums_topic&nodes=23&updated_after=any&sortby=relevancy&search_and_or=and Personally, I don't use Humbrol (can only use acrylics, and they stopped 226 in the acrylic line) so cant testify to the accuracy, but I have used Vallejo. and Xtracrylic and they seem ok. Someone did do a comparison chart on BM a while back, might have been in the paints sub-forum under the Tools & Tips section. At present I use Tamiya paints, and one of their recommended paints in a kit was XF-5, bit dark, but looks ok! I'm not one for total accuracy anyway (especially if it cant be seen), and besides none of my kits get exhibited, and no-one else in my house is a plane nut so no else knows the difference! 1 Link to comment Share on other sites More sharing options...

Thanks Ed I thought it would be the proverbial can of worms. I’ve always used Gunze Aqueous, H55 I think it is, but my old jar has run out and they’ve apparently changed the colour a bit. I’ve found a tin of Humbrol 226 in the paint drawer and wondered if it was goer as it is labelled interior green. Thanks again James Link to comment Share on other sites More sharing options...
Graham Boak Posted March 4, 2022 Share Posted March 4, 2022 It will depend upon the aircraft. What are you wanting to do? (Not that I know which ones H226 is good for, but somebody will.) 1 Link to comment Share on other sites More sharing options...
ckw Posted March 4, 2022 Share Posted March 4, 2022 It depends - there is no single "interior green". If you look at the work done by Dana Bell (sorry don't have the link to hand), each manufacturer seems to have their own approach to interiors. For example, I'm currently working on a Vindicator, and in this case Bronze Green (Humbrol 75) seems to be a reasonable choice. Hu 226 might be a reasonable match in some cases.

Space Ranger Posted March 4, 2022 Share Posted March 4, 2022 (edited) From the P-40N Erection/Maintenance Instructions: Cockpit green: The finish referred to herein as "cockpit green" shall be compounded using the following materials: Zinc Chromate Primer – AN-TT-P-656 Tinting Paste – M-542 Color shall conform to ANA Bulletin No. 157, Color No. 601[sic], "Interior Green". (error: should be ANA 611) For the Bearcat, see here: http://www.arcforums.com/forums/air/index.php?/topic/233584-f8f-colors-on-the-bearcat/ Here are some cross-reference charts for military aircraft colors: https://jpr-guide.tripod.com/index.html The chart for ANA suggests Humbrol 226 for Interior Green.

Jackson Duvalier Posted March 4, 2022 Share Posted March 4, 2022 Curtiss used a locally-sourced "interior green" that was (at least to my eye) greyer/browner than standard, I usually mix it from yellow zinc chromate and a brownish olive drab. From what I can see via the internet, H226 is drabber and not quite as green as Interior Green, so it might be an acceptable match for a casual build. I'd be tempted to add a touch of yellow to it for highlights. My guess is that by the time Bearcats were rolling off the production line, Grumman had access to proper Interior Green. 1 Link to comment Share on other sites More sharing options...

I'd be tempted to add a touch of yellow to it for highlights. My guess is that by the time Bearcats were rolling off the production line, Grumman had access to proper Interior Green. Curtiss and Bell did either mix or got a proprietary mix for their cockpits and interiors; the Curtiss green having a yellowish cast and the Bell green having a more blue-grey cast. My fellow Texan Mike, aka @Space Ranger is also correct that interior or cockpit green was basically a mix of yellow zinc chromate and the tinting ;paste, which IIRC was black; based upon the amount of black added, the resulting interior green, aka ANA 611, could and did vary quite a bit, but as Dana Bell has pointed out, there is no record of a supplied paint sample being rejected in WW2...sooo mix away! I use enamels and the Modelmaster ANA 611, interior green, and the old (read best!) Humbrol 226, U.S. interior green are very good matches for interior green, ABA 611, FS 34151. Gunze Mr. Color 303 US interior green, FS 34151 is also a very good acrylic. There are several other paint suppliers that offer this color, but the ones I have listed are the ones I have and have used. I also mix my own, as many others have done, by combining YZC with black until I get the desired color. The Bell interior green is a little harder to mix, as it has a blue/grey cast Mike Yes, Grumman did use the ANA 611 interior green for the Bearcat, including the inner surfaces of the gear doors; IIRC parts of the wheel bays were also interior green- you can read Tommy Thomason's Tail Hook Topics website article on Bearcat colors for everything a modeler needs to know.

BS_w Posted March 5, 2022 Share Posted March 5, 2022 In the "Curtiss finish specifications S-517 - all export airplane -1939" and "S-615 - P36 and P40 airplanes", in the EMM P-40F , Curtiss gave the following formula for interior finish paint called "cockpit-green" or "yellow-green finish" · zinc chromate primer 1.0 gallon · enamel, black 0.1 gallon · aluminium paste grain 320 4.0 ounces · toluol 2.0 gallons In the EMM of P-40N, the aluminium paste was removed and it was tinted to match "interior green ANA 601" 1 Link to comment Share on other sites More sharing options...
Mike Starmer Posted March 5, 2022 Share Posted March 5, 2022 I just checked my brushed sample of Humbrol 226 against the ANA 611 sample in Monogram's camouflage book. 226 needs a small amount of white or cream as it is too dark and green to meet the standard. Certainly too dark as is for a model interior. 1 Link to comment Share on other sites More sharing options...

Certainly too dark as is for a model interior. Yes, it is kinda on the dark side; To be honest, my original tin has only been opened, stirred, and sprayed once to see how well it matched my FS595a chip chart, but I have saved it for any 1/48 models I build, as I think it's OK for the larger scales.

fishplanebeer Posted March 6, 2022 Share Posted March 6, 2022 I can't claim this is to be a panacea but on my P40 and my current F6F-3 I've used Colourcoats ACUS09/Interior Green and it looks OK to me and does the job in terms of it being the right colour green that it should be. Of course others who are looking for far greater accuracy may well, and will, dig considerably deeper to get an exact match by type/manufacturer/year of production etc. Regards Colin.

Antti_K Posted March 6, 2022 Share Posted March 6, 2022 Hello guys, I studied an Airacobra, which is in its original paint. The green colour in the cockpit and on landing gear legs is darker and more olive than Hu 226. I created my own mix using Hu 150 as a base. Correct colour shade NCS S7020-G70Y looks like this: Hopefully this is of interest. Cheers, Antti 1 Link to comment Share on other sites More sharing options...
Seawinder Posted March 6, 2022 Share Posted March 6, 2022 From my research, P-39 cockpits, at least early ones, were Bronze Green, so definitely different from "Interior Green" or tinted Zinc Chromate. 1 Link to comment Share on other sites More sharing options...
Antti_K Posted March 6, 2022 Share Posted March 6, 2022 Hello Seawinder, this is P-39Q-15-BE, AAF serial no. 44-2664. What do you think? Bronze Green or something else? Mike (72modeler) suspected, that the colour might be "Bell Green". Cheers, Antti Link to comment Share on other sites More sharing options...

One question hard to answer: what exactly was "Bell Green?" According to this thread, it was just a local variation of "Interior Green," presumably some sort of Zinc Chromate/black mix: https://www.britmodeller.com/forums/index.php?/topic/69013-airacobra-bell-green/ 1 Link to comment Share on other sites More sharing options...
