That was designed and defined to handle AARRGGBB values of $FFFFFFFF 
(max 256 for each color channel and alpha), and that fits perfectly in a 
UInt32 data type.

I can't remember from memory. Is TFPColor the one where each color 
channel is a Word size (ie: $FFFF)?  When I wrote fpReport, that color 
range was note designed for and I've never seen in used in the 
real-world either.

Well, then I'll say that FPC's JSON needs to be extended to support 
UInt32, as it is a perfectly valid Object Pascal data type.
