If anything, I'd probably say the new Supra a bit too many lines and a bit overaggressive. But then too, these are more of the design trends of late for Toyota. Not even the MKIV Supra was totally aggressive for its looks for its time. We're probably going to get used to this design unless some completely different styling change happens within a few years. What probably is driving most people away (no pun intended) is its looks. The front elements at the grill would work on the Ferrari 488 GTB, but not so much this car. It's usually the front of any vehicle that provides the biggest impression; and if you don't look great up front, chances are, you are not going to be liked very much. I do think the profiles at the sides and rear are fairly nice. Most of my knocks on its design are mostly up front. While I never really liked the style of the FT-1, I never hated it.
Red has always been my favorite color for the MKIV Supra. Since blue is my favorite color, I can imagine this car looking great in a sapphire-like blue or maybe even a sky blue color. Toyota may even tap into their Lexus arm and give it their beautiful Structural Blue color. A warm silver would also be nice. As for racing liveries, one would imagine this Supra in a number of throwback liveries. You know- Castrol (1990s), Denso (1990s-2000), Petronas, AU Cerumo, Esso Ultraflo, and a lot of the classics.
So would I get the new Supra as we know it and as much as we know about it? I probably would. That is unless I wanted to buy a secondhand MKIV Supra in decent condition instead.
