Even if a mineral can be different colours, its streak will always be the same. This makes streak a particularly useful tool for identifying minerals.

Look at the example below. Both the specimens are a mineral called hematite. The one on the left is made up of metallic grey crystals. The one on the right is a dark red colour with a rounded shape. They look very different but they both have the same brownish red streak.
