All icons here are free to use (with credit when appropriate). Most right now are in the Mint-Y style because that's what I use, but I'll be working to add more styles and colors (usually at request).
Created in Gimp (.xcf), but should be compatible with most other image editors.
Fill colors for & change opacity of background layers, and add icon.
