apparently a very basic answer, but that'd prolly also be purple for me, quite enjoy most of the range tbh
like a deep purple is pretty nice, but i also quite like the softer ones too

but also like it doesn't really affect my day-to-day, i don't wear much purple or have many purple things, but i am thinking of dying my hair a lavender-y/lilac-y colour or something (needa check my contract wrt to dyed hair)

pink

i like a nice #f5c2e7 or a #ff00ff

idk, i like more coldish colours, but any is fine, i guess

black :3

Pink. Hands down. But, I have a fondness of blues and greens as well. (Any blue-green combo is good.)

Red, Orange, Blue.

blue (#4c77a6)

Scarlet~!

Blue

Colour like many things is really dependent on context. I dont have a lot of arbitrary favorites.

Acording to the Mii on my switch its green.

teal

purple, somewhere around #3c0d7f but not necessarily that particular shade

Color is a combination of wavelengths of light, so I'm going to take the most ridiculous possible interpretation of this question and say gamma rays are my favorite color.

purple!!

Purple! (and sometimes pink)
