Colour charging means nothing really. Clever marketing and a little fun, no more. Unless the product has heavier fillers to mask swirls which would probably be more beneficial to darker cars, maybe.
Shampoo, Read up on the dodo shampoos and choose the one you probably Fancy the smell of, theyre all pretty good. Sour power is Nice, as it born to be mild.
lime prime is probably your best bet for polish. Easy to use by hand, smells nice and cheap.
You can't go wrong with any of the core 8 waxes from dodo juice. Not much point spending much more tbh, hard candy and rainforest rub are fun to use, smell good and don't break the bank.
You'll get better results with more effort than you will with fancy products
