Why do character colors sometimes suddenly change?


I've seen this used in almost all of the episodes, where during a fight or a
scene the colors of the characters will change almost immediately, almost to
an inverted color scheme, or sometimes a more muted color scheme.

[In this scene](https://youtu.be/LRGMJahRaJc?t=11s), you'll notice that
Josuke's Stand, Crazy Diamond, is normally colored blue/pink, yet during the
fight switches to blue/green, while Killer Queen, who is normally
Pink/Black/Gold, is switched to Gold/Black/Blue (body, gloves, skullpiece).

[In another fight, seen here](https://youtu.be/EZ14-5cJ73s?t=2m10s), not only
does Josuke and Yoshikage change colors, but their stands change color to yet
another different color, with Crazy Diamond turning blue/brown, and Kira Queen
turning Blue/Green/Yellow.

Another example of Yoshikage and Josuke:

Is there a specific reason for doing this technique? Why has David Co
"switched" the colors sometimes during a fight?




From what I know, Araki enjoys playing with various colour schemes, which is
evident in multiple different colour versions of the characters in manga
covers and coloured artwork, which the anime series has followed as it is a
big 'part' of the look and feel of Jojo-series as a whole. For specific
instances of colour, I guess it's mainly to enhance and add visual flavour to
dramatic scenes.
