Sukhoi crafts have camouflage coloring, played around bottomside sky blue color, general for most of soviet/russian crafts. More or less similar full body shade had Kamov naval helicopters (close to which was first gen of coalition tech in really, but sligty more satured than needed). But to be honestly that never was so GUN blue. That maximum was satured after manufacture/repainting, and then naturaly desature to more protective blue gray shade.
If anybody want make it soviet blue shade i advice use it.
Another general commies paint is just grey, videly used in fron aviation and military transport aviation both. (chineses use more bloss shade also)
So i to be honestly not against make it similar to first gen, but please no need so saturated blue, and it should be matt. Or use just gray coloring.
Upd. Yes, sometime it even could be so blue (because, we have wide standards in paints parties ), but that odd and not common, generally it more gray and unsatured. Also Yak-38 had veeeery odd gray-to-blue-to-black coloring.
