The thing about 81 / 82 / 76 is that RLM banned the use of 74 / 75 in favor of 81 / 82 in late Aug '44.
Most of the factories producing 109s continued using the old colors until they ran out of stock. Most of the aircraft were assembled from pre-painted parts. This why you sometimes see mixes of various paint combinations on the late 109s. Not to mention the fact that many field units also re-camouflaged planes according to what they felt was necessary or had on hand. You can see this among Fw 190 Schlacht units for example(most Fw 190 Fs were still in the old RLM 74/75 camo).
There is no general rule for RLM colors late in the war. Basically you'd need specific data on the plane you wish to paint to make any plausible comments. Even then the tones and variations of the colors are as numerous as there were people mixing the paint. There is plenty of room for variations and 'artistic expression'.
Now on the AH's 'darkeness':
For some reason I need to set my gamma in AH to .6 (that'
6), I hear most others commenting on how dark AH is and them having to lighten (+1.0 gamma) the game up.
On the machine I play AH on I have a Radeon X800pro, 24" widescreen lcd. I calibrated the colors using adobe gamma and the auto test feature on the monitor.
For FB/AP/PF I use 'smart shaders' to give the game a more toned down look. Rather then bright green terrain its more subtle etc...
In AH I don't use them, just reduced the gamma to .6.
