Eye brow dye

I dye my hair ginger, cus I love the colour but I also want to include my brows and I know hair dye on your brows is not recommended. So I have been using RefectoCil, but the auburn shade is too dark for the ginger I have atm and the undertone is really purple which I hate as it is very noticeable (at least to me) I have been mixing it with the light brown shade but it doesn’t change much..
Besides that I feel like the colour fades so fast and I need to redye every two weeks which is way too much in my opinion. I also have brown coloured brows so that might give the illusion that the dye fades so fast.

Any fake redheads got tips for this? Or to just stick to brow pencils?
My drugstore also doesn’t sell ginger beard mens dye unfortunately 💔
