Hi! Sorry for the late reply. I haven’t saved the psds but looking at I’d say I sort of had 3 types of colourings.

Neutral/Bright (ex. 9th, 10th cap) - the original caps were great to work with and I only used my basic prep steps and added a selective color layer to adjust the brightness and maybe a little more cyan.

… the yellow-ish one (ex. 1st, 6th, 16th cap) - I tried to recreate it and came up with this. if it’s too yellow try messing around with the Color Balance 1 layer.

… and that blue-ish/purple sort of thing (ex. 3rd, 4th, 11th cap) - which is very similar to the psd I posted before.
