Finally decided to change the wheel colour. Opted for Porsche Neodyme OZ1.
A local garage run by grandad, father and grown up son at RimTek in Bradford did them and was pleased at the price of £380. Normal price is about £50 less for standard colours which I am getting my Yaris cross changed in a months time. I chose it because it isn't an "in your face" gold but a pastel with a hint of copper/bronze.
I was surprised to find that now in a lighter colour the spokes are different. Every 4th spoke has double the detail on it. Even the chap doing them said he didn't notice that when black but lighter and the detail on the spokes can easily be seen. Had it 4 years and not noticed that.
Another point he showed me was they were not fully painted inside along with a set of honda wheels he was about to do. He said some wheel makes are completely painted as mine are now and other makes just do the outside. all just to save a few pence.
