I have currently only 'RGBHex' and 'Theme' in my ODF proposal draft. And
I have put the color-transformations separate from the definition of the
base color (see attachment). That was my guess from the additions to the
Does integrating the color-transformation into my <style:enhanced-color>
would better fit to your intentions? I could change that.
The ColorType 'CRGB' did not get support in the ODF TC right away,
because it is also only a variant of RGB. The same would then apply to
ColorType 'HSL'. They could be converted in the xmloff export filter.
Regarding ColorType 'System' and its 'SystemColorType', I don't see yet
how this can be implemented well to ODF. It would mean to have a
reference to a color table defined at the user or the user's system. And
it is different from CSS4 <system-color> , so specifying by reference
to CSS4 will not work.
What is ColorType 'Palette' and 'Placeholder'? Is it something, that
needs to be written to ODF markup?

Having a UNO interface and integration to the gradient would allow to
develop ODF import/export parallel to other filter. Is that correct?
Do you see a change to get such into LO7.6 (or maybe named LO8)? Or
should we not even try to get integration of multi-color gradient and
theme colors to LO7.6?
The current state of my start with import and export of multi-color
gradient to ODF  does not consider "enhanced-color".
