I associate red light with relaxation and sleep, I’m talking like photo development room red.

Its interesting because orthodox color theory/chromatherapy seems to consider red as excitatory and stimulating but I feel the exact opposite altho there’s a heavy influence of the brightness or wavelength magnitude or something.

Blue is traditionally seen as calming but I associate it more with wakefullness and alert-ness.

Its weird cuz I would find it stressful if the world outside was rendered as red like Mars or Venus or whatever but ironically I have a conflicting intuition that it would make me tired more than anything else 🤷🏻‍♂️
