You can do this through the EditEngine, e.g.

// setting the text color for a range in EditEngine
ESelection aSel(nStartPara, nStartChar, nEndPara, nEndChar);
SfxItemSet aSet(mpEditEngine->GetEmptyItemSet());
aSet.Put(SvxColorItem(nColor, EE_CHAR_COLOR));
pEditEngine->QuickSetAttribs(aSet, aSel);

// for background color
SvxBackgroundColorItem(..., EE_CHAR_BKGCOLOR);

// for the three font category sizes
SvxFontHeightItem(..., EE_CHAR_FONTHEIGHT));
SvxFontHeightItem(..., EE_CHAR_FONTHEIGHT_CJK));
SvxFontHeightItem(..., EE_CHAR_FONTHEIGHT_CTL));
