I must be colour blind

I don't know what they're calling it in your part of the world, but in Canada (or Alberta anyway), the 3 grades of Shell gasoline are Bronze, Silver and Gold. Interestingly enough, the labels on the 3 pumps in no way mirror those colours. Case in point, the Bronze pump has red lettering on a yellow background. The Silver pump has white lettering on a blue background. The Gold pump has yellow lettering on a red background. There's no bronze. No silver. No Gold. I think in other places they just refer to the grades as Regular, Plus and Premium. Maybe it's time for Shell to do that if we're not going to put the colour of the grade on the label. Just my thoughts.
