what exactly was wrong with the x98 colors? "I don't like it" is more like preference than an actual complaint.
I think the two tone look works very well for this design, I wouldn't change a thing.
The issue isn't the two-tone design, but rather the specific colors chosen.
It's always either Dark+Neutral, Dark+Color, Color+Color, or White+Color. Never a White+Neutral option.
But yeah, I guess that's the specific preference they're choosing not to cater towards.
