It is currently too hard to see the banner on the website on the new light / dark themes when Roblox is having issues. It blends extremely well into the rest of the website.
Roblox’s message banners used to be orange, and they were very clear when they appeared on the website. Moving back to that could be an option, and I would assume the existing CSS would also make it a relatively easy change ignoring all of the software engineering process Roblox uses.
