I’m unconvinced with the new yellowish background for the Meta Branded theme.
It’s a little too vivid (It hurts the eyes, to be honest), IMO. It’s hard to keep looking at the page (my screen luminosity is already very low) without feeling uncomfortable. (Maybe it’s just me, though!)
The previous blue color provided a good contrast[1] with the content (even though it was a bit too visually sticky to the eye but overall solid).
I’ve adjusted it to a lighter blue, the dark blue was causing some text contrast issues on the homepage since the jobs banner is pushing down the search box.
I’m less convinced on a large screen because there is a lot of vivid light blue. (I’m wondering if having more bubbles on a large screen would help to avoid having too much blue area (?) )
