Metro Studio comes with over 4000 pre-made icons which you can customize to meet your needs - change the colors, change the size and export them to any format you want. Here's a quick run through of how to use Metro Studio.

The icon is shown (and defaults to your last configuration - so you can maintain color consistency). On the right hand side there are options for shape, size, transparency, rotation and color.

There are various export formats for example bitmap, ico and png. A great tool to prevent stalling applications.
