Hi Albert,

Thanks a lot for the review

> You don't have an icon, which is not optimal [actually i see you have an icon in invent.k.o so the hard part of drawing it seems to be done :)]

I added the icon and I hope I installed it to the correct location: https://invent.kde.org/accessibility/kontrast/-/commit/8a008c1387c0234d5e1d537bdd331007d7b1ff07. It was already stored in breeze-icons but I guess it is better to also have the app icon in the application so that it is displayed on other DEs.

Fixed now

Great ideas, I put them on my TODO list. https://invent.kde.org/accessibility/kontrast/-/issues

I have now changed the kirigami dependency to require an older Kirigami version, since
I wasn't using any new Kirigami feature anyway. But I would still recommend using Kontrast
with the latest Kirigami version since the new version comes with a few Accessibility
improvements ;)

This code was contributed by Carson Black and I have no strong preferences for the coding style
of the methods. I guess changing it back to the traditional style could make sense to follow
the general KDE coding style.
