Sukhoi-27 by Academy

I have started my Academy Su-27.The instruction sheet says grey in the cockpit area but no description. Is it light or dark grey? Just grey. And this goes for the rest of the colors. Being new to russian aircraft I have no basis on the colors to be used. This is a fairly old kit but the fit looks good. Does anybody have any color guide on russian aircraft?

i thought it was a lightish blue/green lol

it’s interior blue green you can find it in the Model Master line of paint.
