Steps to reproduce

1. Click on the ... of a file
2. Click on "Change colour"
3. Select a colour
4. Click on ... and "Change colour" again

Expected behaviour

There should be a button "Reset colour"

Actual behaviour

There is no Reset button.

The only way to reset it is via the color picker and the Eyedropper tool. With the Eyedropper you can get the instance theme colour from one of the other folders or from the (+) button and apply it.

Screenshots

(Yes, the green in the bottom right is my server theme colour. But it was only added after I picked it with the Eyedropper. And even then, an explicit Reset is easier to find.)

Reasoning or why should it be changed/implemented?

It seems like an obvious thing a user would want to do.

Misc comment

1. More generally, I am surprised that folder colours are a client-side feature? I would have expected this to be a server feature, syncing to all clients.
2. Design feedback: the title of the picker could use more padding. It looks crammed towards the top. Also outer border padding is smaller than the padding between colours. ==> Make the outer padding of the entire popup the same as the padding inbetween the colours.
