User blog comment:Dr.funk98/What palette do you think we'll King Crimson?/@comment-26046340-20190221031837

The majority of merchandise depicts King Crimson in the same colors as the colored manga (red and white), and since so far the anime has been going off of the colors used in merchandise I think that's what they'll go with.

This might be personal bias due to me thinking that the red and yellow color scheme is ugly as hell, but I think there's a good chance that that's what they'll do.
