Don't agree

Shouldn't this be also correct without the "the" in the front? Like a general statement... all brown cars are not pretty..? I got marked incorrect...

"Brown cars are not pretty" was accepted for me, so.. huzzah, I guess. :)
And yes, it can be understood as a general statement.

I don't think the colour makes a car ugly, and cars can still look good in brown.
