When activating paint mode from the QuickFolders tools menu the tool button turns into the icon for the palette dropdown, which can be used to select a new color to "paint" the tabs:

the brush is too big, compared with the other icons. Also, in dark mode it may initially show a white brush on bright background.
Adjust the size of the icon so it works better.
