When you are BLIND, what do you see?

@elafina You live in a CMYK color space 😏

@helenS how's that different from other colour spaces ?

@elafina Essentially, CMYK is used for [u]subtractive[/u] color mixing (the mixing of colors on a piece of paper, where blue and yellow mix to give green.
Most color spaces such as RGB or CIE_XYZ or CIE_LAB are used for [u]additive[/u] color mixing where blue and yellow mix to give white.

@helenS my initial reply is real, I refer to sth I'm actually seeing when I close my eyes and push my palms against my eyes for long enough. It begun with some eye exercises. Help me a little more to understand this..

@elafina Oh yes, I know what you mean, it's an interesting phenomenon. Rubbing your eyes increases the pressure within the eyeball, and this pressure activates cells in your retina in the same way as light does. Your brain doesn't know the difference and so interprets the activation as though you were seeing light from the world outside.

@helenS we can see light without light coming from the outside

@helenS Nietzsche had an interesting view of this in his 'Human, All Too Human'. He said to the effect that our mind forms these phosphenes into recognizable shapes in the absence of any object behind them, as we also incorporate external noises into our dreams. He liked this to primitive modes of thought, jumping to the first explanation to mind for any phenomenon, such as a thunderstorm representing angry gods.

@UpForItNow Didn't he find many similarities between those primitive modes of thought and apparently more advanced modes? I believe he called that "atavisms".
