What is the equivalent of `ColorToString` for FMX in Delphi?

Question

In VCL, I could simply call the ColorToString function from System.UIConsts, but this function is VCL only because it uses TColor:

function ColorToString(Color: TColor): string;
begin
  Result := ColorToStringExt(Color, csfIdent);
end;

I would have expected there to be an overloaded version of ColorToString that makes it work for FMX also, but no.

Ah. After searching for a little bit more, I found that there's the AlphaColorToString function within System.UIConsts:

function AlphaColorToString(Value: TAlphaColor): string;
begin
  AlphaColorToIdent(Integer(Value), Result);
  if Result.Chars[0] = 'x' then
    Result := '#' + Result.SubString(1)
  else
    Result := Result.Remove(0, 3);
end;

So that's what needs to be used in FMX.
