Idea of Change Theme Icon
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.
This is the Change Theme icon for Windows 10
. Here we go. Optimized for 32x32 px, these are the simplest icons in the line style. Downloadable formats are PNG and SVG, among others. Icons8 icon pack is unique in providing a huge number of icons designed by the same team of four designers who create the new icons every working day in the same style and with the same quality. Same cool as the Bat Face, huh.
