Marble, being composed almost entirely of the mineral calcite, would have a white streak. The same colour as calcite's streak.
a streak test is a test wheree you rub a mineral across a streak plate to see the color of its streak, which is a better indentifying factor of the mineral than the external color. A scratch test is when you scratch a mineral to find out its hardness on the Mohs Scale of Hardness. This is also another useful identifying factor

A ruby's streak color appears colorless because as a mineral, ruby typically does not leave a streak when rubbed against a streak plate. The color of a mineral's streak is caused by the powdered form of the mineral, revealing its true color when scratched against a ceramic plate, but in the case of ruby, its hardness and structure prevent it from leaving a visible streak.

Its very easy. Read the underwritten instructions1 Clean the ruby with a damp cloth or toothbrush to remove any debris or marks. Dig your fingernail into the gemstone to see if you can leave a scratch. If you can, it's not a ruby.2 Gently scratch the ruby with a one cent coin. Choose an area that you don't mind damaging slightly, such as the underside of a gemstone that will be set in a ring. If the gem marks, then it's not a ruby.3 Scratch the gem with a series of other items. Use a piece of glass and a steel knife. The knife has a hardness level of 7 and should not be able to scratch the ruby. Scratch the red stone with rough sandpaper. If there is no noticeable effect, then the gem is likely to be a genuine ruby.4 Rub the ruby against a clean white porcelain tile. If it's real, the ruby will leave no color or streak behind. It may even scratch the tile. If the stone leaves a colored mark on the tile, it is likely to be another type of substance. The absence of a streak isn't definitive confirmation that the ruby is genuine, but the presence of color does confirm that it isn't real.
Perlite does not have a streak color because it is a volcanic glass that does not leave a streak on a streak plate.
The lack of a streak would indicate that the mineral is harder than the streak plate, or the color of the streak is the same as the color of the streak plate.
