Non-staining temporary hair dye for white hair?

[mamakoukla]

Hello! I have grown my natural colour back in and generally enjoy my dark hair with plentiful grey, white and silver through it (or truth be told white with silver, grey and dark brown(. I do however get the want to dye it itch every so often - probably just eager for a change. I know I would regret permanently dyeing it. Does anybody have recommendations for a temporary colour which will wash out please?

Ta!
