Can an accessibility feature for those with colorblindness or partial colorblindness be implemented please?

As an example: I struggle with the Titan fight in ARR, as I cannot see the contrast between the orange and the purple lines/orange circles on almost all of his abilities.

I understand the fight--but find it very difficult to judge and discern if I'm standing in bad because it's orange on top of orange on top of a faint line of another color I can't see well.

Well--thank you for listening!
