I’d take a S-2000, or Cobalt SS, or any supercar, or Corvette Z-06, or Solstice GXP in yellow, happily.
Under no circumstances would I take any car in champaign/tan happily. There are plenty of darker shades of gold and bronze that look okay, but I don’t think it’s fair to lump them in with tans.
I think orange is a highly overlooked awful color. There’s that terrible Lamborghini creamsicle orange as well as Corky Romano Miata orange. Orange is bad enough that it even makes a GT3 look like garbage.
Yellow is the ugliest, it never looks good on any car. No one ever says “Hey man that yellow really makes that car look sharp.” It is always “ugh man why did you get yellow, you just want the attention.”
