But now it seems the bride-to-be has enhanced her colour with newly dyed red highlights.
The new reddish hue was noticeable when Markle stepped out with Prince Harry in Birmingham last week.
According to celebrity hair colour expert Rona O’Connor, Markle's new 'do is the perfect way to add dimension to her natural dark shade.
“It allows the hair to reflect dimension, especially on dark brunettes that can tend to look flat,” Rona, who has worked with Blake Lively, Debra Messing and Bella Thorne, told PEOPLE.
“Meghan’s colour looks natural, healthy and is low maintenance,” Rona adds. “Her colour is great for a woman on the go, youthful for brunettes in darker shades and easy to maintain.”
We can't wait to see how Markle wears her hair on her wedding day!
