fix result unreadable for colourblind

[jasger9000]

Hello again,

This PR is meant to fix the result page being hard/impossible to use for colour-blind people because the emojis are difficult to differentiate.

Since I'm not colour-blind myself, it would be really great if @q00u would have a look at it since they raised the issue initially from what I can tell. Any other feedback would also be greatly appreciated.

Definitely readable and unambiguous no matter what kind of colorblindness (though I still like the softer blocks vs the checkmarks, if only it were red and blue)

In some cultures, the checkmark means wrong, and a circle is used for 'correct', but then again, this is about English, so maybe that doesn't matter

I could add blocks around the checkmarks and crosses, so the symbol would be black on a coloured cube.

if only it were red and blue

I think blue would be confusing for the majority of people, since green is usually associated with 'correct'
