what's with the differnt colours of polycarbonate.

[seneca]

sorry about having to ask another question so quickly after the first one, but after investigating polycarbonate on the net there appears to be different colours of the thing eg. bronze, opal, clear etc. what's the difference between them, or is it just a personal matter of the colour you prefer? Is the bronze less likely to show dirt or absorb less heat? Bronxze seems to be a bit cheaper as well. Does it have a downside to make it cheaper? what are the pro's and cons if indeed there are any?

thanks.

the opal keeps the suns heat out more than the others.the bronze keeps sun light out (like sunglasses)and the clear is the poverty range.
