Yellow.
Magnetite can be black and it has a black streak. It is metallic and iron ore
Magnetite
The same color as the writing from a pencil, very dark grey or black. Pencils used to be made of graphite
Promethium is so rare and so radioactive I don't thing anyone's ever collected enough of it to tell. It would, however, presumably be a silvery-gray color like nearly all other metals.
Lithium is a soft, silvery metal with a metallic luster. Its streak color is white.
Yellow.
Aluminum does not have a distinct streak color because it is a metallic element. When tested for streak, aluminum will leave a silvery line resembling its natural color.
Magnetite can be black and it has a black streak. It is metallic and iron ore
One common test to distinguish between nonmetallic and metallic minerals is the streak test. Nonmetallic minerals will typically leave a powder streak of color when rubbed against a white ceramic plate, while metallic minerals will leave a metallic streak.
The streak of a mineral is much more accurate in identifying a mineral than color. The streak of a mineral can distinguish minerals with metallic and non-metallic luster. For example, metallic minerals generally have a dark streak whereas non-metallic luster minerals often have a light colored streak.
The mineral that fits this description is hematite. Hematite is an iron oxide mineral that has a metallic luster, is hard, and has a characteristic red-brown color and streak.
