Well, I could find no reference in the scenarios to the @{RGBA} business, but I tested it out anyway and it seems to work fine. Works for broadcast or spoken dialog in the chat window but not for chat-bubbles.

[For those who aren't programmers, I'll explain it in detail]
Where R is the red hexadecimal value from 0,1,2,3,4,5,6,7,8,9,A,B,C,D,E,F (Where 0 means no red and F is maxium red).
G is the green value 0-F
B is the blue value 0-F
A is the alpha (or transparency value) where 0 is invisible and F in fully opaque.

Example (I'll leave you to guess what it looks like! hehe!):
@{F00F}Red! @{0F0F}Green! @{00FF}Blue! @{888F}Grey! @{0FF8}Semi-transparent cyan @{FFFF}Back to normal solid white

Remember, if you are just making a single word or phrase coloured, then you need to use @{FFFF} to reset to normal text after that word.

Incidentally, the system doesn't care if you enter @{ffff} or @{FFFF}. Case is not important.
