Animated Text Example - How to Shake and Rainbow

Hey! Quick question. From the "Animated SpriteFont effects" example from the Start Page, how could I have a text to be Shaky AND Rainbow at the same time? I can only enable one effect at once...

Is it possible to have both effects in one text?

I tried this to make wavy+rainbow as a test but dont work together:

Hello,

This reminds me of runescape many years ago.

 "[offsetY=" & (sin(time * 300 + loopindex * 90) * 8) & "]" & "[color=hsl(" & ((time * 100 - loopindex * 20)%360) & ",100,50]" & mid(RainbowTextString, loopindex, 1) & "[/color]"

Thank you Mr. OneHitWonder
