Martha Stewart signed on with red velvet cake and white icing, Mac used lipsticks and Bert and Ernie from Sesame Street showed their support too.
They are among an estimated tens of millions of social media users who have posted and tweeted a symbol in support of gay marriage.
It’s a variation of the logo for the Human Rights Campaign, normally a bright yellow equal sign on a blue background. But to draw attention to the two same-sex marriage cases the Supreme Court heard this week, the Washington-based organization on Monday changed the colors to a square red box with thick pink parallel, horizontal lines. Red, for the color of love.
Then they invited people to share it.
Tens of millions took the campaign up on its offer, often replacing their profile pictures on Facebook and Twitter with the image.
