>>8796247While many of the USAF greys have a slight blue tint to them, your pic likely makes it way too blue. And/or whoever made the model used a too blue grey. Google up some pics of the YF-22 and you'll see that the grey shifts a lot in how blue it appears, but it's all the same paint job. Colour photography isn't always the smot exact science, our brains sure as hell take a lot of shortcuts all the time with perception, and on top of that computer monitors usually aren't calibrated for shit either here.
>Is there a similar color but bluer that was used on F4s?The F-4 has been painted in just about every colour under the sun, including straight up blues (Konnichiwa JASDF!). For more or less bluish greys the USN has FS 35237 that it seems to have put onto F-4 at some point as part of some paint scheme that's called "Gray Blue". The USAF also has FS 36320 Dark Compass Ghost Gray (often named just part of that) that can look quite blue at times and not at all at other times, no idea if they put that on an F-4.
