Along time ago (cough), I was taught how to mix any colour from tints. This was City & Guilds paint & dec. We only had white paint.I’m in my 47th year of manufacturing coatings , specifically matching colours by eye . Even though there are devices and self learning systems to match colour my customers still want the one person who says that’s spot on .. we are one of only a handful of companies who still do it the “ old fashioned “ way ..
I’m one of only a very few people who now have that skill . Within 10 years I reckon that ability will be gone as no one is being trained to do it anymore .because of technology..
But even after 47 years I’m still learning..
Perfection in all things can never be reached .
We only better ourselves by learning what is possible through mistakes
Needless to say manufacturers don't sell these anymore.
