OptionalbgOptionalcolorsOptionalcustomColors the theme offers beside its scheme, in order: Office lists them as Custom Colors in its color pickers. Not inherited from the base theme.
OptionaldarkOptionaleffectThe theme's effect style list (<a:effectStyleLst>) — the effects a shape/chart style
(<a:style><a:effectRef idx="N">) resolves against by position. Each entry is the (possibly
empty) list of effects applied together for that style — one <a:effectStyle>'s <a:effectLst>.
OptionalfamilyWhich theme this is, across the files and versions it appears in. Not inherited from the base theme.
OptionalfillThe theme's fill style list (<a:fillStyleLst>) — the fills a shape/chart style
(<a:style><a:fillRef idx="N">) resolves against by position.
OptionalfontsOptionalformatOpaque capture of the source theme's format scheme — the raw <a:fmtScheme>
fragment (fill/line/effect/background-fill style lists) — replayed verbatim on save so
idx-referencing shape/chart styles (<a:lnRef idx="N">, <a:fillRef>, <a:effectRef>) keep
resolving against the same source definitions instead of a regenerated, differently-ordered
list.
Set only when the source fmtScheme contains something fillStyleLst/lnStyleLst/
effectStyleLst/bgFillStyleLst can't fully represent. The lists that can be
represented are still populated, so the theme draws with them.
OptionallnThe theme's line style list (<a:lnStyleLst>) — the strokes a shape/chart style
(<a:style><a:lnRef idx="N">) resolves against by position.
OptionalobjectWhat a new shape, line or text box starts from. Stated, it replaces the base theme's whole,
so {} means none.
The theme's background fill style list (
<a:bgFillStyleLst>).
