4:47 AM...and my brain can't think of the name of the primer color...

That funky yellowish green used inside of gear bays, on the inside surfaces of gear doors. Something oxide. The project I am working on has the inside of the gear bays and gear doors painted an odd orangish brown color...not at all attractive. That ? Oxide will look much better but I can't think of the name of it to look up a good RGB color code.

Maybe that's a sure sign that I should go to bed.

And that's it! Chromium Oxide. No wonder my tired brain could not think of the name.....more than 2 syllables. Chro Me Um....that would be 2 plus 1 is 4 or something like that syllables.

Thanks Ferry....now the plane will have nice Chro Me Um Oxide gear doors and bays and what ever else I decide to slap that sickly green color all over.

Zinc Chromate primer ages to a odd 'orangish-brown' colour with time and exposure
to dirt; oils and other chemicals that can be found in landing gear bays like leaking hydraulic fluids!!

Yep, in the time before the EPA ruled everything you did in the Military (paint-wise) we used to have cases of Zinc Chromate in the Shop to use for Corrosion Control on all our Ejection Seats and Canopy Frames. But that's in the past now. . .:salute:
 
Ah yeah! Zinc chromate primer is very attractive IMO. It is iconic to aviation in both civil and military. Love that unique flat green color as well as it's protective qualities. Yellow looks good too but I like the green more.
 
Zinc Chromate is the paint you're looking for OBIO. Interior Green came about by mixing Zinc Chromate and Black. There was also a Zinc Chromate Yellow paint used, as well as a Salmon Pink. One has to have reference on all interior greens used on aircraft throughout WW II, they were about all different, there was a Bell Green, a Bronze Green, a Republic Green, you get the picture.

For an ideal reference on interior and primer colors used by the USAAF and USN in World War II, read this and the subsequent articles.

We used it on some interior spaces on ships and on subs too in the Navy.
 
Hi Obio, let's see

USA Interior Green FS 34151 (RGB) 113, 112, 72.
USA Yellow Zinc Chromate FS 33481 (RGB) 213, 186, 87

These are the references I have for them, although the yellow one can be a bit iffy as it was only one coat and the final color would depend on the original surface (bit of a minefield there).
And thanks God for the expresso machines!!! :d

For all who may not have been there.

Simmers Paint Shop is the Bible among many of us for reference to colors. Go there and register. Go to Colour Swathes in the upper left and scroll down to the nation or FS number you want. There are RBG and HEX codes along with color swathes for about any color you wish.

I do thank you all for your input and info. Unfortunately, the project I am working on has thrown me a snag....the bulk of the gear wells are colored via the MDL material settings....and for some odd reason, the MDL file can not be read by Martin Wright's MDLmat...so I can't tweak the material color to reflect the Yellow Zinc Chromate....so, the gear doors will have to remain the odd orangish brown..it doesn't look bad...I just like the look of the Yellow Zinc Chromate better. I did enhance the detail in the gear wells as much as I could, so there will be an improvement over the stock stuff.

It's odd that the stock MDL files can not be read by MDLmat, yet I was able to use MDLC 117 to add reflective texturing to the planes (3 models in this project...going to be a LONG restoration project...but well worth it in the end). Having reflective texturing really elevated these planes up several notches.

I think what you are trying to remember is Zinc Chromate anticorrosion coating - common in WW2. I guess that they now have some other preservative... to judge by the interior bay coatings in US Navy aircraft...often white... (don't know what compound this is)
