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 🤷🏻♂️
I think color theory is esoteric and at least subjective, if not completely made up. I occasionally see some red mood lights in peoples’ homes on the window sills when I go out in the evening. I more or less associate that with ‘red-light district’ if it’s more than one window. But I like it. Blue would be more a color a gamer or live-streamer uses to light their gamer’s den. But it’s also the color of the night and the endless sky or ocean. Also more blueish hue adds to concentration. I’m split on the whole topic. If I want to concentrate or get some work done, colorful light is too distracting. I need proper white light for that. Other than that I just choose what I feel in the moment. And I like amber.
