The only reason I type this is because I got a black sacred boost from trade up. At first I thought it was pretty cool, black is worth a fair amount, might get a nice trade for it. I went to inspect it and this boost is almost invisible, even when inspecting in the main menu.

This could give an actual advantage in game, for example, player with regular boost sees an open ball with another player heading towards it from the other side. This player cannot see the other players boost, so would probably assume they will arrive at the ball first because they don't think the other player is boosting.

In situations where someone can see someone with "an invisible boost" from the side, I don't think this will be a problem, as they can actually see the speed, however, I think the problem will become evident in situations where players are heading directly towards each other, as its harder to judge speed, and in lower ranks where players might not have got a grasp on the speeds of cars entirely, and this will add more confusion when trying to learn.

tl;dr, some of the new painted boosts are seemingly "invisible" from a distance, which could potentially give players an advantage in game, and I was wondering if these boosts would be changed to be made more visible in a future update.
