I've been thinking a lot of dyeing my hair lately but i didn't know how to do it other than this. I mean it might help a lot before i do something stupid and regret it later. 1- this is how i look if i dyed it black
2- this if it was Brown
3- this is the original color (Like in my real picture)
I think black is too dark, but a darker brown than the one on the picture would look good on you, I believe, since you have a light eye color, it creates a good contrast and highlights your eyes. You have also fair skin, which goes great with a dark brown.
Personally I'd go for brown since black is such a hard colour to come back from you'd end up needing to bleach it, brown will probably need a bleaching process but it shouldn't be anywhere near as harsh as what you'd have to do to come back from black :) You could try a semi perm colour in black but do a strand test first - I can't stress this enough! I bought a bright blue that was meant to wash out after 6 washes, I'm on about my 20th wash and it's just now started to fade to green, I am so glad I strand tested to know how long the colour lasted lol
