I know that carcolors over 126 where removed at times we had A LOT of bugz, in an effort to eliminate the bugs. As we don't experience crashes anymore, maybe it would be a good idea to bring back the old colors? They are used in other servers and don't seem to cause any trouble over there. Then again, I am not a coder, and maybe I am missing out on something.

I just think it would be nice to put, lets say, a nice flashy Red151 as a primary color, or a nice Blue5523.

Well, tell us what you think.

Well I remember, before the 126+ were blocked, it was very colorful everywhere in the server. Yes, as Alpha stated, it is possible to use 126+ colors as secondary, which makes the use of cars like Bullet that more interesting.
I guess we will need Admino's advice on this one..?

I'll see what I can do, those colours are known as "unstable", however this has likely changed in 0.3a.

Again, I'll look into it first and see what can be done.
