This is beyond unacceptable

Discord. You say you care about accessibility, but that doesn't mean anything when there are dozens and dozens of posts about people who are physically unable (or greatly struggling) to even use your platform because they're getting eye strain, headaches and migraines caused by your rebrand. I'm not directly affected, but I know someone who's been getting headaches because of the new colour and the vast majority of posts here currently prove this isn't an isolated case.

People not liking new branding always happens, but this is more than that. This is causing actual pain in a sizable number of people. This isn't a problem that will fix itself over time. You can't tell people who get migraines to stop getting migraines, ignoring the feedback won't fix it. If you really care about accessibility, for the sake of your userbase's happiness and wellbeing, turn it back, or at least give the option to toggle it, because as it is, it's unacceptable that it's lasted this long without (to my knowledge) being properly acknowledged by the team.
