I agree this would be awesome, I’m sure JinRyuu will add more customization as that seems to be a big focus of his recently with Hair, Ki ability customization and so on (changing aura colors and all) which is awesome and I would also love to see this in Dragon Block C at some point in time. Having just played the latest release of Dragon Block C I love it and love all of the progression. I reckon that your idea along with casting animations for all of the different ki attacks would really polish it off.
I reckon adding something like having 1-3 solid colors would be neat. So say the spiral attack has 2 twisted beams of two colors you choose (example 2 blue or 1 blue 1 green as you mentioned for how it works), and the middle beam being dark blue or something like that which is the only good way I can see it working rather than a cluster rainbow of colours. I think this would be good to add later after everything else has caught up with development and JinRyuu’s written plans. Definitely a suggestion worth taking note of.
