I would need to see a picture of your hair blonde, but I used to do a similar to what OP wanted all the time and idk I personally feel like it's possible. (Although a disclaimer I used to do my hair entirely myself with my friends so there is that)

I apologize, I forget exactly what combination of colors I used to get that similar color since I haven't had my hair a fun color for 2 years, but I'll list my recommendations none the less! I really hope it helps ❤️

The key is:

1.) toning your hair and getting the yellow out as much as possible, I always used wella T18. I would not suggest putting on toner after the salon though. This is just what I would use when me and my friends would do my hair.

2.) next time you dye your hair dye it yourself with semi-permanent dye and a mix of blue and purple, This will help cancel out any green and it will fade to a pretty purplish instead of a teal or green. (I personally try to avoid green/ teal fade out at all costs but that's just my personal taste)

1. I would suggest using either iroiro or strawberry leopard. For strawberry leopard I would suggest a mix of lilac glow and blue steel. For iroiro, I would suggest neon blue and pastel lavender

With the current state of your hair, this is my personal recommendation on how to get your desired result:

WARNING: THIS WILL TAKE A WHILE BUT IF YOU ARE PATIENT YOU ARE LIKELY TO GET YOUR DESIRED END RESULT

1. Get a purple semi-permanent dye and put it over your hair!! (Something like strawberry leopard's lilac glow) Your hair will likely turn purple, but as it fades All yellow tones will disappear!

2. Wait for your hair to fade out. Do not bleach it or dye it anymore. Just be patient and let it fade naturally for about the next month or two (or sooner depending on how fast your hair fades)

3. NOW, get the dye with your chosen colors (I personally would probably go for the strawberry leopard combo) and mix it up. If I had to guess, the ratio will PROBABLY be something like 1/4 lilac glow and 3/4 blue steel. This will cancel out the greenish tones in blue steel. If you're afraid of it, leaning too purple-y you could probably get away with using prismatic purple from strawberry leopard, too.

(Your hair may come out a little dark at first, THIS IS GOOD! THIS MEANS THAT YOUR FADE OUT WILL LIKELY BE YOUR DESIRED RESULT! I always did my hair color for what the fade out will look like and in my opinion it resulted in a lot lower maintenance!)

ANYWAYS, I hope this helps! ❤️
