Can anyone tell me what hair colour I want?

I've been spotting people in town with the most AMAZING hair colour and I neeeeeeeeeed it.

I am very fair with ash blonde hair colour naturally.

The colour I've seen is... well, it's a sort of lilac / silver / grey. It's NOT purple. It's very very pale. I don't want to get mauve my mistake. Any advice?

Not a clue on the colour but I would be searching the hell out of Pinterest with the colours you've already said until I found the one I wanted
