Our branding has changed recently - actually our primary brand colour is #1DA1F2 
Thanks for this feedback, we’ll be sure to pass it along to the design team.
Apologies for the layout issues, particularly with the media upload documentation (that’s something I am responsible for, and will fix). With such a large quantity of content that we’ve ported to the new stack, there are a number of places where we’ve got some broken markup, and we are working on this now. Do keep letting us know when and where you see issues, we need the help to make things better!
