Different color for currencies

Instead of having just a number at the corner, basic currencies could have their colors changed instead. This makes it much easier to see the difference

For example:

Normal augmentation orb (blue) > greater augmentation orb (lighter blue) > perfect augmentation orb (white to match with div/annul being high tier currencies)

Normal exalted orb (rusty gold) > greater exalted orb (shiny gold) > perfect exalted orb (white)

It would be nice, but please explain to me in what situation you are dependent on differentiating between those currency types at a glance?

If you pick them up, your item filter will show the difference, if you put them in your stash it auto-sorts it into the currency stash-tab and if you want to use them you can also simply pick them from the correct slot there.

I bet these small numbers in corner is just a placeholder.
These orbs will get their own fancy texture soon.
