Usually they're fairly accurate, but I just bought 5 litres whose
colour is almost exactly correct when first applied, but which then
dries to a much lighter shade.
Usually emulsion paint *darkens* as it dries.
It's not just a little bit different, it's very much different.
Anyone know what they might have done wrong?
I'm planning to paint a test strip, let it dry, then take back the
strip and the paint.
But it would be good to know possible causes of the error.
Could it just be the right combination of dyes, but simply too little
of them?

Magnolia doesn't, it goes lighter.

The machine that mixes the colours is run by a computer, if there's not
enough of one particular dye to do a job, it won't begin.
The colour you ordered is what you got and if you went to ten different
places and had it mixed by them, they would all dry the same colour,
providing they all used the same base, to put it another way, you've picked
off a colour chart the size of a postage stamp which is printed on different
paper using printing inks and it's never the same as the finished paint.

The OP says 'colour matching' in the post subject, this suggests that
they used the colour matching service - where they scan an item and then
try to match a colour to it. Rather than them just picking from one of
the colour swatches. We've had that done before and as the OP said the
final dry colour is a pretty good match for the finished colour(not
perfect, the are limits to what it can manage, but certainly a good
match).
My guess is that either for some reason the machine can't mix a good
match or that the scanner didn't pick up the right colour for some
reason.
worth I think taking a painted strip back to the store and see if they
will redo it.

Also, I was urged to buy the same batch recently lest matching issues
arose. I couldn't be bothered and as it arose, there's no difference to
my eye between Dulux, Crown and Wickes magnolia. They're completely
interchangable and I've even filled missed bits with no sign of overlap .

possible is that the wrong base tin was used.

reds/maroons. A would-be customer got very upset with me when he asked
'Can you match colours?' and I started my answer 'Yes, but ...'
because he wanted a yes/no answer and I wasn't prepared to give him
one.

certainly be taking it back :-(
The annoying thing is that the match *is* perfect - when the paint is
still wet.
Usually they seem able to adjust for colour changes while drying, but
not this time.

medium green (30 year old paint, at a guess).
The stuff sold to me dries a pastel green.

The young lady said she would sell me two 2.5 litre tins on special,
then found they were out of that tin size, so sold me one 5 litre tin
instead.

of that sort of 'discussion'.
I've been around long enough to know there are damn few absolutes, but
some people won't accept "probably close enough" or "Probably not" as
an answer.
And sometimes when I wanted someone to say "likely, though no guarantee"
the person wouldn't say that - presumably too scared after some earlier
incident.

paint mixer did not do the job fully and when the user gave it a good
stir, the correct colour was obtained.
