This Change Theme icon is a responsive icon. This means that it's optimized for four resolutions, from tiny 16x16 until highly detailed 80x80. The style comes from the latest Microsoft Office, which makes it perfect for any Windows applications, in particular, those with ribbon toolbar control. Unlike other icon packs that have merely hundreds of icons, this monster icon pack contains 15,100 icons, all in the same style and quality.
This icon represents change theme. It includes two square shapes overlapping each other. Both squares have two smaller squares with a line across the top of them. One square has a lot of dots in the bottom half and one with less dots just across the top and inside the smaller squares.
