Is there a way (ideally using Sketch) to do a single color overlay over an icon that has multiple colors – while preserving the original icon's different shades?
I'm trying to turn the blue folder icon into different colors (green, purple, etc.), but I'm trying to do it more elegantly than having to go through and recolor each shape individually. I'd like to be able to change the color of the folder and have it respect the opacity of the icon underneath.
Should I make the original blue icon into a transparent gray? Then somehow mask the overlay color? I tried that below in Sketch and couldn't get it to work.
