They used pulsing flashtubes like for your strobe and I think each color was sequential making dodging and burning a question. But a ring around is sure a nice thing if we ever played with Photoshop and AA sure seemed to think so. RGB were the colors making it an additive head producing richer colors in the print they said and others agreed. Filtering a white head is subtractive color CMYB BAD, BAD, BAD! An LED safelight seems logical and are out there but as the wavelength is intrinsically red I can't see how it could be used as an enlarger head which needs a lot of Green, Blue, even white which is all colors. Pulsing flashtubes in my damp darkroom would make me nervous. I believe the exact same head was used for B&W as well as color. Mark Rabiner
