Whereas salt-and-pepper noise is typically just white or black, hot pixels can be of a pure, saturated color, while dead pixels are black. Hot and dead pixels occur for a very different reason than salt-and-pepper noise and should be handled using the [[Preprocessing#Hot.2FDead_Pixel_Filter\|Hot/Dead Pixel Filter]], which works before demosaicing.
