Depends on the lenses, of course. There are still enough crappy new lenses on the market so.
Color rendition is also impacted by the sensor, assuming digital cameras.
Since I don't know which lenses you talk about, hard to tell. I do have some really old ones, 80-200 f 4.5 from the late 70s and an equally old 300 f4.5. Both render color just fine, no difference between those and new Nikkor lenses. Sharpness wise, those old ones are easily as sharp as any new one, lab test confirm that. And the limited amount of glass gives them, a totally subjective, clarity new lenses don't have. Bot that I would d be able to tell just from looking at a printed or processed picture.
