Fashion fans quickly took to Twitter to laud the three women for wearing shades of violet, perhaps a nod to bipartisanship and unity. The color is created by mixing blue and red – the hues of the Democratic and Republican parties. Purple has also been one of the official colors of the suffragette National Women’s Party since 1913, per the organization.

According to Cosmopolitan, Harris may be paying tribute to Shirley Chisholm, the first Black woman to elected to Congress in 1968 and run for president in 1972 on the Democratic ticket. Chisholm used the color purple in her campaign materials.
