/////      import { colorParsley } from 'colorparsley';
/////
/////    FORWARD CONTRAST USAGE:
/////      Lc = APCAcontrast( sRGBtoY( TEXTcolor ) , sRGBtoY( BACKGNDcolor ) );
/////    Where the colors are sent as an rgba array [255,255,255,1]
/////
/////    Retrieving an array of font sizes for the contrast:
/////      fontArray = fontLookupAPCA(Lc);
