Hypothetical Observation, is a proposal for a show which could be in the Observatory space. I was inspired by Wittgenstein’s monograph Remarks on Colour (RC 1, 2), and my essay discusses: Sky light (blue sky), the colour of light source (sky).

I think that when Wittgenstein uses blue sky he originally wants to show the light source, but the light is from the sky, not the light of blue.

The Sky and its Colour is a proposition that what we sense, intrinsically we name the colour sky-Blue. If we did not give that name to sky, then what would we receive or perceive? However, if sky were named instead of blue, red, green or even a tribal noun galagala or bleble, what would we expect?
