Changing the Health/Healing Text Color

I have been playing with the text colors in the textcolor.xml file and everything was fine and dandy until I tried to change my Healing Colors. It may be a 2 part issue though.

I do not know for sure that I am changing the right attributes to get what i want to change. In particular I'm looking to change the "Health gained" that falls from the top of the screen by default.

I tried modifying the following to no avail:
HTMLFont name="self_healed"
HTMLFont name="other_healed"
HTMLFont name="self_healed_critical"
HTMLFont name="other_healed_critical"

So then I thought there might be a different text ID, so following similar to the "<HTMLFont name="stamina_gained"" I tried creating a "health_gained" entry and this still didn't work.

Just wondering if anyone has been able to change these colors and if it is even possible, Or I am just doing something stupid.

Thanks for the help!
