Bug description

We have seen some examples of grey text in dark mode and find them really hard to read. A suggestion would be to make them white or really close to white.

Ant design has some accessibility issues on some components https://ant.design/components/empty?theme=dark

If we can fix those upstream it would be great if not we should fix it on our side instead.
