What colour is the ink in it? The EXACT tint of the exact shade of the exact hue? What is every atom and molecule in the biro?
Impossible to know, impractical to obsess over.
It's 12 cm long, blue ink, red casing. A Bic. That'll do.
I wonder what colour the ink is without human brain impulses or a yellow sun.
Colour is a property of light, so, it's not really that the ink is blue at all. It's the light that reflects off it that has the colour. It only has the
potential to reflect light that's in the wavelength of blue, but it has no colour itself. In other words, everything except light is perfectly black (no colour).
I was thinking about this the other day. I wish I had the physics background. I'm very good with math but I know nothing about physics.
