RNZAF WW II National Insignia FS clours

[richplo]

Dears, I am cooperating with Eduard M.A. company on decals and as we prepare Limited Edition of SBD-5 Dauntless with RNZAF marking included, I am looking for the FS match of the blue in the roundel to get them right. I got some information it should be close to FS 25056 with FS35109 look when faded. Can anyone help? Many thanks!

Hi Richplo, you have come to the right place. This has been an ongoing discussion here for many years.
Personally, and I must stress 'personally', I am nowadays content to apply decals which I understand use FS15056 as fresh 'dark blue' RNZAF roundels. This appears identical to FS25056 on www.colorserver.com.
Because of the long history of RNZAF roundel blue being rendered far too light by model and decal manufacturers, I (again) personally would not bother with a 'faded' version because it will look like an incorrect light blue roundel. However, FS35109 does have a somewhat 'grey' hue which I understand occurred in the fading of blues like NS & Semi-Gloss Sea Blue and possibly insignia blues as well.
I wouldn't apply such faded insignia to a model myself any more unless there was very strong photographic evidence for doing so, considering that different aircraft probably faded differently and fading probably occurred unevenly over individual roundels.
There are folks on this site know a great deal more than me about the technicalities of the colour(s).
Hopefully your 'Limited Edition' SBD-5 will have decals for aircraft with artwork and names so far not depicted by other manufacturers? As you will know there was a marvellous selection of such artwork and names on our SBDs.
Regards, Wally.
