WebCore with fnc component demos Delphi 12

In Delphi 12, TMS Webcore /fnc demo builds fail because of invalid color reference. ie clDarkGray, clDarkRed,clLIghtSaberBlue...Is there some setting I missed to avoid this? This appears to be a Delphi 12 only issue. NO problems with 11.3. System is a fresh Delphi 12 only setup. Demos without reference to fnc components build without error.

We will release v2.4 with this addressed in the next few days
