Most ideal dye for lashes/brows?

[cablerunner]

I'm going to dye my lashes and brows but I'm not sure what the good options are. Some have suggested to buy the just for men beard dye

I was originally planning to dye my lashes black but since they're already long, the transformation from light brown and not so visible to black will be too noticable and I'll probably look aspie and/or gay asf

So I'll be dyeing both my brows and lashes dark brown
