The login and settings pages of Instagram and WhatsApp will feature this new logo in the same color as their respective apps (so the font will be green on WhatsApp and a purple gradient on Instagram).

“This brand change is a way to better communicate our ownership structure to the people and businesses who use our services to connect, share, build community and grow their audiences,” Facebook Chief Marketing Officer Antonio Lucio wrote in a blog post announcing the change.
