One colour stood out at Joe Biden's inauguration on Wednesday: purple.

Several women - from Vice President Kamala Harris to Former First Lady Michelle Obama - opted to wear shades of purple to the inauguration. 2016 Democratic presidential nominee Hillary Clinton and Senator Elizabeth Warren also arrived at the ceremony in purple, while incoming First Lady Jill Biden wore it for Tuesday night's vigil at the Lincoln Memorial Reflecting Pool, reports USA Today.

This fashion choice was not a mere coincidence. Purple - a mix of Republican red and Democratic blue - has long been seen as a symbol of bipartisanship. The colour also has historic ties to the women's suffrage movement, according to NPR. Along with white and green, purple makes up the colour of the suffragette flag.

According to CNN, the colour purple also has an added significance for Ms Harris. She chose it as a nod to Shirley Chisholm, who was the first Black woman to run for president under the Democratic party and the first Black woman elected to the US Congress. Ms Chisholm often used purple in her campaign flyers.
