Light Brown works for me
"Light brown is perfect for me. I am a blonde with dark brown brows that are greying. Light brown blends and covers my eyebrows beautifully. Use a light hand when applying the brow color so it doesn’t clump and look heavy. Combing brows with an eyebrow/eye lash comb helps distribute the brow gel. Other brow gels are easier to apply. Almay Brow Styling Gel works. It looks natural, lasts all day and easily washes off at the end of the day."
