I tried Color coding for Folders and set the background to a color a did not like and wanted to go back to transparent and set the text color - but I did not find how to do it - HEX #000000 did not work because this resulted in color black - I found a solution in choosing the same color as the standard background so that works for me - but is there a way to set the color to transparent?
In that folder's properties just select the Hex number of the background color and press the Delete key to change it back to default.
thank you very much - that worked
