Bringing theme colors to ODF

[Regina Henschel]

Hi Tomaž,

I have attached a "using elements with names" compared to "using a list".
In case of "using a list", referencing a scheme color would be done via 
index and not via name.

Please tell me, what is your preferred solution.

Kind regards,
Regina

The <draw:color-scheme> element has a draw:color-scheme-name attribute and a draw:scheme-colors attribute.
The draw:color-scheme-name attribute helps consumers to organize color schemes in an application.
The draw:scheme-colors attribute is a space separated list of twelve sRGB colors in #rrbbgg notation. They are usually used in the meaning dark1, light1, dark2, light2, accent1, accent2, accent3, accent4, accent5, accent6, hyperlink, followedhyperlink.

The <draw:color-scheme> element is usable with the following element: <draw:theme>.
The <draw:color-scheme> element has the following attribute: draw:color-scheme-name.
The <draw:color-scheme> element has the following child element: <draw:scheme-color>
