For the working color space we opted for the the one with widest gamut (aces p0) :
This is because that is the goal of the research project (to study how realistic naturally lit interior environments in virtual reality are with cognitif and perceptif tests that will be provided from another lab) and so we want the most photo realistic/ physically correct values and so that implies working with a wide color gamut, but i think aces describes a set of specifications to be used, not just the colorspace but also implies using a filmic tonemapper so i have no choice over what tonemapper to use right ?
With another color :
I will have to admit the difference in the new colors is less subtle but it is there ?
