Wash in hair colour for ombre hair

[TimeForMy10thCuppa]

So we are fast approaching the half term holidays and I thought I was go for a wash out hair colour. By the time we go back to school I will have gotten used to it/ it will have washed out.
The problem I have is that I have an ombre style ATM. Dark brown at the roots to a blonde at the bottom.
If I go for something like a pink/ turquoise Will it stain the blonde? I love my hair the way it is but am getting bored but don't want to commit to a different colour.

Also I wanted to go for a darker grey, but can't seem to find one. Any colours anyone would recommend for my very light Indian skin?

Posted to soon.
It doesn't have to be grey willing to venture out as long it washes out rather quick.
Thanks in advance.

Cheeky bump

You might have meant that you only want to colour the blonde bits in which case this is irrelevant but......I'm no expert but I'm pretty sure there's no way to temporarily colour dark brown hair pink, turquoise or grey. You would need to bleach your hair before colouring it. I think the only wash in/temporary colours which will work on dark brown hair might be ones which give your hair a slight red or purple tint.

If you meant just colour the blonde bits, I have dark brown hair with lightened ends too and did once put some rose gold/pink temporary colour on my hair. It definitely didn't stain it so as long as you buy a wash in wash out colour, you should be able to get some colour on the ends without it staining. Not sure if temporary blue colours would be a bit green and whether grey would perhaps just make it look a bit dull/taupey brown against the rest of your hair without getting it done professionally. Pinks and purples might work best.

Darn it. Was really hoping I could find something that would colour all of my hair.
Never mind.
Would you mind sharing what brand you used? I saw some by bleach London. Soft pink and a rose gold. Looked lovely. But not sure if that is what I need.

Thanks for the reply by the way.

I use the Bleach London ones in rose gold
I have dark hair on top and a few blonde bits underneath
The dark bits barely change colour but the blonde bits go very pink, I love it
