Flashing RGB light are legit the most annoying shit ever.
I just have a black box for a case and my peripherals glow a dim solid color (so I can see them in the dark) if at all.
I largely mean flashing in general, it's all just distracting to me.
Also most people I know personally actually like the rainbow madness.
Even if they try to match their keyboard and mouse, they'll still often have a unicorn box.
They also love putting their rainbow tower on top of the table, I really don't get it.
A friend's uncle even has a case the height of a table, like bro... Is there no end to this?
I used to have a cheap mechanical keyboard that has side rainbow RGB panels that can't be turned off. I thought that would be turned off when I turn off the backlight. Nope.
