If you look afound you will find you will be anle to get white, grey & black in the right sizes.
The coloured stuff is for scaffold/roll cages and too thick.
I asked Steve ages ago as he has done a little research into pad reproduction in his time.
He said the coloured stuff isn't out there.
I had a look anyway and found his research was sound.
Red, yellow, blue will leave you looking for old padsets as doners.
Some pretty cheap original old no name padsets do come up on eBay.com now and again . You just have to keep an eye out.
