San Francisco's City Hall was lit pink during the city's Women's March Saturday evening.
Tens of thousands of people took to the streets in San Francisco Saturday afternoon, where they packed streets and public transit in protest against President Donald Trump.
The protesters filled the streets during the demonstration as some headed toward City Hall.
Once they got there, many of the protesters were greeted with pink lights illuminating City Hall.
Mayor Ed Lee confirmed in a tweet that the building was lit pink in support of women's rights.
In the past, city officials have used lighting to show support for causes and in solidarity with other cities or nations.
The San Francisco march was one of several protests being held across the country Saturday, the day after Trump was sworn in as the 45th president.
Many of the marchers continued on even after rain started to pour down on them Saturday.
The San Francisco Chronicle reported the Women's March was scheduled on the same day as an anti-abortion demonstration Saturday, but the two groups shifted the times of the protests so they would not overlap.
