"But red is our BRAND!" shouts someone from BBC's design department.
It's 2018, and by now everyone has spent a lot of time using digital applications. We've seen a lot of red things on our computer screens and they mostly are warning us that something went wrong. After a while, certain colors began to carry with them strong connotations. Just look at bootstrap, a common frontend framework, and how they connect color with meaning:
"But red is our BRAAAAAAND!"
Okay, yeah, red can be a brand color. But take a look at YouTube. How much red is on their page? Almost none. They get that red is an especially annoying color when used excessively. They reserve it for the moments that matter. Also, they don't hijack the color of your status bar on Android.
"But red is..."
...we get it. It's easy to go overboard with color. More color means more "pop" right? And marketing people love "pop" and "flash" and making logos bigger and clawing your eyes out with whatever ploys they can devise.
According to usage studies, red is the most attention-getting color, which may be a reason why we use it to show that something is wrong. It's also why marketers and CEOs love using it everywhere. But with great power comes great responsibility.
Don't let branding leak into universal conventions. People use their phone more than they use a particular website, so if your website overrides a convention that exists on their phone, users are going to get confused.
