I'm certain that white wasn't always air/wind, considering it was literally the only color in Blake's Dust cilp in No Brakes that could have possibly made the rock clone.

Her Dust clip had the same six colors that Weiss keeps in Myrtenaster:


 * Red (Fire)


 * Dark blue


 * Yellow (Lightning)


 * White


 * Purple (Gravity)


 * Light blue

The two blues are taken by ice and barrier. Even if the light blue was a different shade than the one Weiss has in Myrtenaster, it'd be steam or water or something, so still not rock.

White was likely responsible for the rock clone in volume 2. So, I don't know what they've done with rock/earth Dust as of volume 3. List of minerals in the Eart's crust by percentage

1. https://en.wikipedia.org/wiki/Feldspar (60%) (Streak color: White)

2. https://en.wikipedia.org/wiki/Quartz (12%) (Streak color: White)

3. https://en.wikipedia.org/wiki/Pyroxene (11%) (Streak color: White/greenish white/gray)

4. https://en.wikipedia.org/wiki/Amphibole (5%) (Streak color: White/gray)

5. https://en.wikipedia.org/wiki/Mica (5%) (Streak color: White/colorless)

What do all of these minerals have in common? They all leave a white streak. 72% of the earth's crust will leave a pure white streak while the top 5 will be mostly white.If you don't know what a streak in then look here: https://en.wikipedia.org/wiki/Streak_(mineralogy)

If we look at this from a scientific point of view then we can see that the vast majority of the earth's minerals leave a white streak and therefore white is the ideal color for Earth.
