These only mention a EZRhttps://www.transpares.co.uk/how-to-fin ... olour-code and the colour is Gris Aluminium.
These https://www.chipex.co.uk/colour-match-search/?cc=ezr say the colour is the same, for both EZRC and EZR.
Halfords say that EZR is Arctic Steel https://www.halfords.com/motoring/paint ... aint-300ml where the first link didnt even mention a Arctic Steel nor a EZRC.
