I want to create a cube with three colors: #F26558, #999C9E, and #ECE9E9. Each color should be applied to opposite sides of the cube. For example, if one face is #F26558, the face directly opposite to it should also be #F26558. Similarly, #999C9E and #ECE9E9 should each be applied to opposite faces of the cube. The cube should have a clean, smooth surface with evenly distributed colors.
