Can Pulsing White Light Reveal Its Component Colors?

[cragar]

Is it possible to pulse white light from a source and see colors .

Not unless you use a prism. However there are optical illusions which seem to produce color from pulsating white light. If you watch a rotating disc with alternating black and white stripes painted on it, your eye will tell you there are bands of colors.

like a benham top.

It's a very subtle effect and not a basis for actual 'colour synthesis' like you'd need for colour TV. The strength of the effect is very subjective and depends upon the individual. I reckon it works on the different time constants and linearities of the colour receptors in the eye.
A prism or some diffracting structure (an oil film or lines on a CD surface, for example) works much better!
