Not so on Mac. The core simple color picker is excellent and *extensible*
[0, etc.]. The user can install many types of color pickers that become
part of the core color picker's dialog.
This is why everyone implements

This is only true for platforms that don't natively support CMYK picking,
but true nonetheless.
So, +1 from me for crafting a custom color, swatch and color palette/scheme
picker. Since QGIS has to deal with multiple platform inadequacies in this
area, it is good to bring all user's functionality up to the same level,
all while integrating better with the app. Qt certainly has the facilities
to make almost any type of picker that's needed.
However, a very big -1 for such a custom picker *replacing* access to the
For example, the very first option in user Preferences in the latest
Photoshop is allowing the user to choose the default color picker (between
Apple's or Adobe's) . I think having such an app-wide setting, with the
custom picker as initial default, and the ability to pop up the system
color picker from within the custom picker's dialog, is critical for
cross-platform user experience. Otherwise, we risk really annoying existing
users by forcing their color workflow to ours.
