I don’t know how many have tried out dark mode, but if you have you might have seen that the color contrast of topics(?)/messages you have created are on a purple background with black letters.
I think this might be a bug? Or at least unintended. Almost all other text with purple background is white. Black on dark purple is not only annoying and straining for the eyes but also not very accessible for people with different types of visual impairments.
Hmm seems like it is when I send private messages and replies to private messages on pc and Android but it is not consistent. My tester call and messages under it (that I have written) shows up as a black background with white text, but my group message shows up with a purple background with black text.
Examples when talking to ribbot bot (where background is always purple forr my own messages):
