On a Club visit to Selly Oak in the very early days, somebody asked Val Page what the correct colour for Ariel maroon was. His reply was something to the effect of "Don't tell me all of the parts on your bike are the same colour, surely?" From this, we may deduce that Ariel had the very same problem as you now have. Fortunately, it also tells us that if the new colour doesn't match to perfection - your bike is closer to original.
