I don't think you're going against us -- you're right there with us
We all agree it's the paints that are off, the sculpt and art direction are solid!
Ororo needs
white hair. Has nothing to do with the design, but all in the color.
And you're right, 'Roro isn't redbone (am I allowed to say that? I don't mean anything negative about it just a good way to describe her skin undertone in this paint). I don't care if they make her more mocha, chocolate, or whatever. Just not as dark as TChalla because she has always been a touch lighter.
Send her back to paints! While at it, flip flop the white and silver paneling on the suit. Perhaps Ang was concerned it was "too much white" and that's why her hair is gray. Easy fix is to swap the color scheme.
