Colouring The BOTA

Edward Tarot Hands

Okay I know there have been a few other threads about this but none of them specifically answered my query which is thus:
I'm thinking of buying The BOTA trumps to colour and I'm wondering those of you who have done it would you recommend following the colouring system or would you choose your own colours
I think it would be much better to choose your own colours but then I know The BOTA is pretty heavy on colour symbolism
Advice please
