As shown in the video
I created a new empty folder and defined the tag to assign it to the empty folder
I used an eyedropper to pick up the Excel file color #15c24f and applied it to the marker icon color
When I put the eyedropper on the empty folder again to pick up the color, the color value changed to #39f276
Obviously, the two color values are inconsistent, which means that the icon color set is not the icon color of the final application effect.
Also when I set the icon color to gray, empty folders end up purple
Is this a bug?
The color you choose will be used to tint the original icon.
It's not going to make every pixel in the icon that exact color. That wouldn't work properly and would look awful, as all shading would be lost.
The windows 11 folders have a slight bottom to top gradient on them, the colour picker will read different values depending on where you pick the colour from.
