Hi @Paul_I, welcome to SharpTools family and glad to hear that you enjoyed SharpTools!
You can customize the icon and color of the tile by editing the dashboard, tap ... at the top-right corner of the tile you want to customize, select edit, check Icon and/or Color, and tap the icon/color picker below to customize. See screenshots below for details:
These tile customization options are available to Free users as well, and you can do a lot of cool things including the tile PIN security protection with your free license.
I’d also recommend you to check out the dashboards created by other users. There are lots of inspirations and creative ideas in the “Show Off Your SharpTools Dashboards!” thread, and don’t forget to share yours later.
