Is It possible to dye gray hair beige with natural hairdyes?

I use mostly natural stuff, nightblooming sells one but i add extra yellow dock to get more blonde. However it doesn't penetrate like henna and every 6 months I use the weakest dye I can find. I used oilio last time.

Never worked for me, I've done tea rinses and noticed a slight change but that's due to doing them for a long time I'm assuming
