Black on white and white on black (whatever hex colors those actually are) will look fine. But different applications will use the accent colors differently. For example, some might use black text on a colored background, and others may use colored text on a black background. Some tools even use “bright” colored text on a different colored background. This is masked in most cases by iTerm2’s “Minimum contrast” setting, but when I tried to design a color palette with good contrast with that setting off, I found it to be very difficult.
