I once printed a color photo (from an inkjet printer) on color paper. The photo had white it in, but there is no white ink…and no white on the page. But, I could see white. What is the name for this phenomenon? Thanks!
(I asked once before, but I can’t find it via the “search” feature.)
Subjective colo(u)r
This link seems to define that term as the phenomenon when there is motion of an achromatic (black and white) object, such as a disk.

But, what I describe is different. If anyone is familiar with what I describe, how does it occur? How much ink of this and that will make the eye “see” white where there is none?
Sorry for the brief (and not necessarily accurate) answer; it was late.
As I understand it, the human visual system implements something similar to the the ‘auto white balance’ in video cameras (or perhaps it would be closer to the truth to say that the cameras implement something similar to the human visual system). In the absence of any other context, the brightest objects are considered to closest to white; this effect is responsible for the way that a great many visual illusions work.
This link explains it a bit, but in the context of illumination, rather than colour-washed printing, but I would imagine they’re two sides of the same coin.
