more Paint is needed now for same success rate. For a good success chance 80-100 can for low level colors, 200 for mid range, 300 for the upper ones

That sucks.
I *CAN* use more paints now, even higher ones but then I need hundreds of cans to have a real chance!
BUT the TT Value of the Paint is added to your clothes or returned in PED, so the only thing "lost" is the markup.
Colors suitable for me:
Orange, Yellow, Blue, Olive, Steel Blue,Green, Purple, Brown, Turquiose, Navy, Violet Cream
Not in my range but possible to try with 500-1k cans
Pink ,Light Green ,Mauve, Umber ,Deep Cadmium ,Burnt Umber ,
Dark Wine ,White,Red,Black,Crimson
I color for free atm, just ask 50pec tip for decay and my time.
