Colour is only the colour that is ADDED by the maker, as the natural colour is a milky white, some use different colours to denote hardness but others don't.
You can even make your own very easily, any colour you want as well, moulds can be made from loads of things, as the material does not readily bond to anything.
Basic poly is basic poly, there is but a few not hundreds, they become hundreds and thousands when mixed differently.
The colour has NO bearing on performance.
You can buy very small quantities for diy use, and not very expensive either.
The point of a BUSH is to allow movement depending on where fitted, and to CUSHION the NVH, the harder the bush, the more the NVH, it is that simple, harder will last longer but so will any NVH.
Each bush manufacturer has thier own idea of how hard they should be.
Whatever make you choose it will be a vast improvement on std bushes, that is for sure.
Anyone who has seen GLADIATOR, BATMAN etc has seen poly props made in Norfolk, currently he is making practice claymores(AP mines) for the aussies, has recently finished hand grenades for war films, stacked out with work and these are all poly.
