Yes, the 'RLM 02' (Humbrol No.31) does look a tad dark in the pic, probably due to using Aperture Priority, with forced flash, at f29, against a white background. It looks OK 'in the flesh' though, and is a very close match to the old Humbrol Authentic Colour RLM 02 ( I've kept the tin for over 30 years, as it exactly matches the RLM colour chip). I'll have a look for that Humbrol 240 though Wojtek, as it could be useful.
Anyway, the main painting is now done, and I'm pleased with the results. The hard/soft edges I was aiming for have worked out quite well, although it's difficult to see in the pics, and there were only two small areas that needed a little adjustment , which was the 'tight' soft-edge demarcation immediately behind the cockpit on the port side, This was very slightly too high, and not level with the area further aft. The other area was a slight 'kink' on the inner edge of the RLM 71 'triangle' on the starboard wing, but these have since been corrected.
I had intended to leave the masking on the yellow areas, but as one lifted when removing the other masks, I removed them all, and I'll just clear coat these areas too.
The pics below show how it looks so far. Next step is some detail painting, followed by a gloss clear coat, which I'll try to get done tonight, although I have a lot of domestic stuff to catch up on first.
