I checked it with:

style={viewModeSelection === VIEW_MODES.List ? 'transparent' : 'neutral'}

But it still looks a little bit buggy too me 😕

I'm working on it.

Edit

Nevermind. i forgot too adjust one line.. 🤦🏽

Looks good! 🙂

Thx, will check it asap

These examples don't look so good:

The buttons in thumbs view should remain transparent without hover.
In the list mode the button position is not fully correct, you can see a little blue gap the the top. Maybe we should change the active and hover color, so there is a highlight on hover visible on the buttons. Do you want to try at a better solution with out color scheme?
We also have the color variants of the primary colors in our brand guide.

The buttons in thumbs view should remain transparent without hover.

Hm. Like that? This also doesent look good IMO.. or maybe I have to give it a little time and think about it.

No, with your change there were not transparent by default anymore for me. I would prefer if they stay transparent "until" they are hovered.
And in the list view they should still look good when the line is hovered and the background is therefore blue. That was also off like in my screenshot.l.
