This is a very opinionated and I would say personal issue.
I also think most syntax schemes (the highlighter is perfectly fine, let us be technically correct) are very wrong for my own purposes.
This thing is the wrong colour, this looks like a candy party, some colours should be used only for such and such thing, strings should always be this colour, etc.
So, I made my own syntax colour scheme with my own conventions, and it is great.
But I don't try to convince anyone to use my colour scheme. That would be preposterous and intrusive.
