Very odd. Here is a session I just ran with my display set to
16-bit color. It works perfectly. (IDL 5.2)

IDL> curve=Loaddata(1)
% Compiled module: LOADDATA.
IDL> x=Findgen(101)
IDL> Device, Decomposed=0
IDL> LoadCT, 13, NColors=101
% Compiled module: LOADCT.
% Compiled module: FILEPATH.
% LOADCT: Loading table RAINBOW
IDL> Plot, x, curve, /NoData
IDL> PlotS, x, curve, Color=Findgen(101)

Cheers,

David
