Pastel pink hair - which brand/shade to dilute?

I'm pretty sure Directions Flamingo pink goes that colour when diluted. And SFX Atomic Pink.

On this pic, it looks more like it's a colour that's faded down and so it's lighter on the ends naturally. Or, the ends were lighter before hand. All you'll need to do to replicate it is have three pots, each one a bit more diluted than the last. Don't need two different pinks.

Thank you! I was thinking maybe something like SFX atomic pink,  Directions flamingo or Crazy colour Pinkissimo.
& yeah now that I look at it more it does look like maybe she had a warmer base at the roots and lighter ends.

I'd say directions carnation pink would work too. Undiluted it's quite bright, but does look like the hair near the roots of that picture. You need to avoid a yellow base for a pink like that, otherwise it'll turn more of a salmon colour I think. Or if the base had some yellow, wash it with a good purple shampoo (I use bonacure) to keep it looking pink.

Pinkissimo def goes this colour! I dilute mine weaker than this to make it even paler. I have a slight yellow base and it still looks a cool pink, and also covers some mint green patches. I just made a post in the pinks section if you wanna see what mine looks like.

Thank you both of you!
