Im trying to replicate some specific RAL finishes and im not sure of the physically correct way of working with CIELAB values and gloss levels. Never had a client supply the data in this format before so im not sure if the conversion to rgb would be accurate given the smaller gamut of RGB within CIELAB.
RAL 7038 delta E: 4,49 Gloss level:13 L: 76,88; a: - 0,16; b: 1,68
RAL 5008 delta E: 2,23 Gloss level:15 L: 33,93; a: - 1,53; b: - 7,04
Do i simply convert the lab to RGB?
Does real world gloss translate directly into a glossiness value in corona?
e.g. gloss level 13 would that be 0.13 in corona?
This feels like something dubcat would have experimented with but he hasnt been around for a little while.
