Very simple example:

1. Drop RichViewEdit, RVStyle, ColorDialog and SpeedButton components on

the form.

2. Declare constant for ApplyStyleConversion:

const

  TEXT_COLOR      = 7;

3. Write an event handler (of clicking the SpeedButton):

procedure TForm1.SpeedButton1Click(Sender: TObject);

begin

  ColorDialog1.Color := RVStyle1.TextStyles[RichViewEdit1.CurTextStyleNo].Color;

  if ColorDialog1.Execute then

    RichViewEdit1.ApplyStyleConversion(TEXT_COLOR);

end;

4. And finally you should handle OnStyleConversion event like this:

procedure TForm1.RichViewEdit1StyleConversion(Sender: TCustomRichViewEdit;

  StyleNo, UserData: Integer; AppliedToText: Boolean;

  var NewStyleNo: Integer);

var

  FontInfo: TFontInfo;

begin

  FontInfo := TFontInfo.Create(nil);

  try

    FontInfo.Assign(RVStyle1.TextStyles[StyleNo]);

    case UserData of

      TEXT_COLOR:

        FontInfo.Color := ColorDialog1.Color;

    end;

    NewStyleNo := RVStyle1.TextStyles.FindSuchStyle(StyleNo,FontInfo,RVAllFontInfoProperties);

    if NewStyleNo=-1 then begin

      RVStyle1.TextStyles.Add;

      NewStyleNo := RVStyle1.TextStyles.Count-1;

      RVStyle1.TextStyles[NewStyleNo].Assign(FontInfo);

      RVStyle1.TextStyles[NewStyleNo].Standard := False;

    end;

  finally

    FontInfo.Free;

  end;

end;

That's all!

Hope it helps.
