Sadly my local motor factor which stocks this wonder paint is shut due to the bank holiday, otherwise I would have popped in and done a reverse calculation on what broad spectrum a single tin of this stuff "covers". Suffice to say that it isn't used by discerning car enthusiasts who want an exact match for a certain colour. That should quantify the "close-ness" of the match or not as the case is.
And before you jump on your high horse - read the thread title and the reason for the title - this thread was started to discuss/show how out of date the Halfords paint references were, which has already been proven ie the much praised RAF Kinloss MRC list is no longer fully available from Halfords in their "off the shelf range".
This thread was never intended to update the "off the shelf car paint" list - if someone wants to do that, good luck to them. Personally I use Pheonix in rattle cans and have no problems with them.
I have worked with paint for long enough to know that it fades, and certain colours fade worse than others, especially those containing cyanide compounds (red paints), and that certain depots hand mixed their paints in their own special way and that paint batches are never exactly the same, and greens look different in photos and early colour photo developing favoured the blue/green spectrum, (add your favourite excuse here) ,,,,,,,,,,,,,,
but an incorrect colour will always be an incorrect colour.
If you can't admit that, then you are short sighted.
