Paint colour matching woes.. anyone here worked in the paint industry or know what might be going wrong?

Thanks for the info.
I've already taken them the bonnet once and that resulted in the tin of mint green paint. I'm going to take the bonnet to them again and either leave with some matching paint or a refund on atleast the mint green paint. I'll also bring a screwdriver and some bits of card so I can check before I drive away as it's turning into a saga of repeated 50 mile trips.

Is there really no one nearer ?

Noone who's an HMG supplier.
I'll probably end up going 1k from an experienced car paint supplier tbh.

Given that nisocoat 2 is advertised as being available in ral, bs , automotive and fleet colours I don't see why it's such a problem them producing a paint which is a very close match. You'd think they could just spectrometer it, mix to to whatever code comes up and that would end up a lot closer than what they've mixed up so far.
Certainly the 2 aerosols and touch up pot I've had from the likes of motip and holts were able to get acceptably close via me just ordering online via the 04318 code.
This is why I think they've gone ridiculously wrong somewhere and seems to be blaming the specific product saying it's because it's an industrial coating when the info from hmg themselves indicate that it can be mixed up just as well as automotive paint.

Different ways of mixing for colours are used of old and modern, one by weight the other by percentage (I can't remember which way it changed). A good paint mixer (The man not the machine should be able to do it on the fly) but finding one is the trouble. Doing a side or the whole car might be the answer to matching.

All the schemes use scales, standox had all the colours on a microfiche and occasionally they’d send updates for certain mixes. Probably all on a hard drive now.

Your "spray outs" look satin in finish. Is it just the photo not showing the gloss or are they trying to sell you a water based basecoat? If your supplier knows anything about paint, they would certainly see the difference. Its not a shade issue after all, its a totally different colour.
