but anyway it’s mean to be wrong, funimation blue ray have dark colors cause it have crush black and overbright so if you “copy” colors to the kai footage which don’t have crush black you’ll have some colors too dark than others
you have to think that (cause it’s not totally accurate like i said with some green in the yellow for example) if you have a dark blue with a crush black footage, your goal is to get the same blue as bright as it was crushed black so a middle blue instead of the dark blue

What? I don’t think that’s how the algorithm of the program works.

if i am correct the program goal is to “match” colors so he will alter your source colors until match your reference, but the things is that the “reference” you use is oversaturated, overbright and crushed black so even your reference already have color alteration, the tool copy saturation etc…

the hardest things in color correction is not only to take color in consideration, but also the footage, for example cels, carddass etc don’t have the same brightness , contrast etc than the dbox if you want the same colors you also need to adjust those to match them

for example if take this screenshot

you see details in the white (where the guys are running) but not in the dark as it was crushed
here the source

if you watch the regraded bluray

you have effectively recover dark things but you now less see things in the white things as you can’t almost not see anymore the details i was talking before
that’s why your references have to be “perfect” else you’ll loose something if you don’t have perfect reference you’ll have to alter manually colors and work with tone yourself to recover the dark things without destroying the white
