Umm no I don't agree at all!
The Basic Color editor is just that - allows basic control. Also the size of each color zone can be adjusted. It is not set!
Capture One Express (for Sony) only contains the Basic tab.
Capture One Pro contains Basic, Advanced and Skin. If you have Pro, then simply bypass the Basic tab.
I agree with David, and I'm a bit puzzled by Jochen's statement about "very bad colors". I'm not sure what he is referring to. Given his annotated tool crops, the Basic color editor has not just 3 equal sized portions of the Hue scale, but a bit more refinement where specific colors can make a difference. And, as David said, the sectors are not fixed, they are user resizable. But basic is pretty, well, basic.
The Advanced Color editor allows to additionally confine the adjustments to certain saturation ranges, which allow to make some very targeted color adjustments that should blend in naturally with other Hues.
The Skin Color editor concentrates its efforts on skin tone colors, a subset of all colors. It's intended for yet another type of color adjustments.
Then, besides the targeted color adjustments editor, there is another tool, a completely different tool. The ColorBalance tool basically adjusts the Whitepoint HSB values, if wanted it can do that separately for shadows, mid-tones, and highlights.
Different tools for different types of adjustments, targeted versus generic color changes.
These tools do not produce bad colors, it's up to the user to adjust colors or not.
