This Nocny pejzaż icon is made in Material Design style developed by Google. This style is based on extremely simplified shapes, thin two-pixel lines, and is optimized for 24x24 px. Unlike other vector icon packs that have merely hundreds of icons, this icon pack contains 4,300 icons, all in the same style and quality.
This icon contains two triangles representing mountains. The left triangle is slightly larger and overlaps the one on the right. Above the right triangle there is a crescent moon shape, with the crescent being on the right side.
