That might answer it. I suppose that if some "stealth" settings exists, they are highly hardware dependent. Better to get TEMPEST rated hardware then... check government surplus... I've had reports of TEMPEST class computer cases being sold with power supplies real cheap...
My question was not "would it work in all instances?" but rather "had this tactic been implemented successfully in *some* instances?" Not that I have ever heard...
Hopefully I am not feeding this troll too much.
Or, to the contrary, is it reasonable to assume that modern Tempest equipment can work around theses impediments almost all of the time, therefore making any attempts at this futile? No modern equipment can detect radiation that does NOT leave a Faraday cage.

Varying the colours does not reduce RF radiation. It just obfuscates it by making the radation given off by the three colour beems and their cables equal in extant (at least, far more equal).
