Two images from Jeff Ethell's "P38 Lightning in World War II Color".
First is a P38E that is fairly new. The camo is still dark etc.
Second is a stateside training unit F or G that looks the worse for wear. Lots of touch up paint etc.
I would imagine the Pac OD/Gray birds somewhere in between with the care given to combat ready birds vs the tropical weather.
I initially went with darker panal lines on Dottie, but ended up lightening them up as it looked better to me both from outside and inside the cockpit looking out.
