BG-siluet is a background in Powder Game (implemented in ver7.8) and Powder Game 2 (implemented in ver4.8, known as BG-silet since ver6.0). In BG-siluet, the screen becomes monochrome: the background becomes white, while the elements become black. Whenever an element and/or object has motion, it makes a little blur, just like BG-light, but shorter. Objects, blocks and the grids are always black. Elements that have motion will be colored in slightly darker colors (some can have greater color saturation; such as acid), otherwise, it blackens.
