Slate is a low grade metamorphic rock generally formed by the metamorphosis of mudstone / shale, or sometimes basalt, under relatively low pressure and temperature conditions.
The color of slate is largely determined by the amount of iron it contains, but it is normally a shade of gray. Slate normally forms in basins between convergent plate boundaries. Often, slate is used to describe shale but the two are different in that shale is actually converted into slate.
