P3D Re: pulfrich effect

Quoting from Tony Alderson, quoting from
Ron Keas (digest 3094):

It seems to me that (the) one big advantage of Pulfrich is retaining 
the original colour. The major disadvantage of Anaglyph is that the 
colour sensation at least is drastically altered. 
If I read this right, using fairly saturated filters with a Pulfrich 
source will lose the colour, so it might have been better to use 
anaglyph, and not have to whizz about so much!
