I read his “Cognitive Mumbo Jumbo” section and couldn’t pull a thing out of it. Maybe it’s just me. No disrespect intended towards the man, but sometimes he seems determined to write cryptically.

@kofa you didn’t answer my question regarding the profile that you use in the base primaries tab to handle colors better, is it the working profile or the exporting profile ? because I didn’t find a clear answer in the previous discussions. I mean in sigmoid it is clear that Srgb works best for handling high values back into gamut.
Lol almost everytime I ask Troy something I feel instant regret; but hey, we’re here because of the mumbo jumbo mate.

Thanks for a good reply @kofa.
But it’s all quite complicated for me; I’m going to bow out, wait for it to be “productionised” then probably come back to it.
Good luck finishing it off.
There is a reason why he isn’t on this forum and the way he often talks down to people is completely unacceptable.

He may seem harsh but I learned a lot from him actually so let’s not get off of our main topic please.
I echo that sentiment and if we are lucky someone will produce another excellent video showing us how to use it

Eary_Chow said above that a larger space is often better:
Yes.
As for explanations, I find Troy’s writing very hard to follow. Sakari, Eary_Chow and Jed Smith have helped a lot. Jed has a very nice Wiki with visualisations.

Aurélien’s perceptually uniform space:
I don’t think so. Not because I actually understand the process deeply (I’m learning alongside you, that was the whole point of this project), but because those who know don’t use it.
No, the xy coordinates are different. Primaries always have RGB coordinates where one component is 1, the others 0. That’s why they are primaries: they define the axes of a coordinate system (they are the basis vectors of the space).The xy coordinates, which determine exactly what shade and how pure a shade of red, green and blue they represent, are different. They are the corners of the triangles drawn inside the ‘horseshoe’ xy chromaticity diagram.
