A presentation often uses a scheme, or palette, of interplaying colors - through their use in various styles, non-style color choices, like for some animation effects, or even the color palette of the slide background image(s). Also, while bug 152652 is unresolved and style categories are missing, direct formatting. I often want to create a presentation from a template, but while I like the layout of the template, I feel the color scheme / palette is not right for me. Maybe I want greens with cyan decorations instead of Reds with Orange. I'm missing a dialog for editing the document "color scheme". Note that style inheritance can't be used instead. This is both because we don't support multiple inheritance of styles; and because an individual style only contains one or two relevant colors, not a palette of them. I'm not sure a color palette needs to be represented in the ODF or not; if it isn't, UI for editing a color palette could collect its constituent colors from various styles and put them together in a dialog, possibly with previews of the interplay of the colors.
Note: _h
Note this is not about color schemes for the _UI_, but for the presentation _contents_.

For the results up to now: in a master build, see Format->Theme, which is present in all modules, but in Impress, it's only active in Master views.

So, it seems there's only been very preliminary work, since no theme corresponds to what we see on the Master slide, nor does selecting a theme affect the Master slide or the document. But - it's nice to know someone has been working on this.
Format > Themes become enabled in master view. Changing the theme affects the "Theme Colors" palette in any color picker- and the applied colors.
