These minerals are quartz, feldspar, mica, and usually hornblende.

color
The color of the powder left on the rough surface by a mineral is called its streak. The streak plate is a hard surface that helps to determine the different shades and characteristics of the minerals that is rubbed on it.

Color is what you observe when you look at a mineral. Streak is the color of the mineral when in a fine powder form. This can be observed by drawing a sample of the mineral over an unglazed porcelain tile and noting the color of the line left on the tile.
1. Minerals don't (or at least don't usually) have "powders" inside them. They can BE powdered, but they don't generally contain powder.2. The color of a powdered mineral is usually at least somewhat like its color before being powdered (though generally of a more pastel shade).3. The color of a mineral depends on what it is; specifically, many minerals get their characteristic colors from transition metal ions, and the color of a transition metal ion depends on a) what transition metal and b) what its oxidation state is.

The same mineral can come in a variety of colors and different minerals can be the same color.
