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.
How should FPC's JSON support something, that is not supported by
JSON?
The problem is not in JSON.
Native Javascript supports 2^52 (or so) integer values, so every UInt32 value
should fit
if written properly.
FPC's JSON supports Int64 and even QWord in FPC, so a UInt32 is definitely
supported.
If the colors (a UInt32) is currently written as Longint (signed 32-bit)
then of course a range check will follow, and this needs to be fixed.
The easiest solution is simply to read/write it as Int64.
