Beige and amber; and more in general warmer colors since lights in the ones tending to blue look blurry to me unless i'm very close to the source of the light.

Purple.

Octarine

Ultraviolet. It makes other colors look cool. And it kills stuff.

Yellow! I used to hate it but after I started playing Splatoon it really grew on me and now it is my preferred color of choice

I don't have a favorite color. I guess I have a preference for certain colors in certain places, but I like them all.

Purple.

Orange. Pure orange, yellow orange, neon, burnt. Not so much red-orange, but I do love oranges that have a bit of a pink sheen, like padparadscha sapphires.

Dark green, mustard yellow, purple and whatever this is called:

And colors that give me nostalgia like traffic light yellow or a specific shade of light blue.

Jeans

For odd reasons I like a very specific shade of green (around 525nm, I'd call it "emerald") - it shows a lot of promise in reducing migraine headaches. It's an example of what's called photobiomodulation, which is a technical term for using low-energy infrared/visible light to signal your body to do certain things (as opposed to harmful high-energy radiation like UV rays). Being in green spaces can also help people's mental health and that's still being investigated.

Another example is using red light therapy to help wounds heal faster and improve skin quality. Red or infrared light exposure for therapeutic reasons was investigated by NASA and adopted by the US Navy.

So it's probably different reasons than you were expecting in a longer answer, but I love those colors because they heal people :)

I like dark blue and purple equally.
