ATTN: Spike

# (just for reference) == Ctrl+K in mirc to put the color code symbol in

now to have a background color, you must specify a forground color first (#0,15)

, denotes end of forground color, and start of background color

irc colors work in many strange ways:

#0-#15 for forground color // the code currently converts to this one, which is not the "proper" irc way, read the next one to understand. Still need to support it, just not output as it.

#00-#15 for forground color (note #010 to #015 is not valid) --- this is the "proper" irc way, because I could say "#11+1=2" (which means I want 1+1=2 to appear black (1), but instead it will come out as indigo (11) and look like this: +1=2)

background examples: (note

#0,15 (white forground, light gray background)

#00,15 (white forground, light gray background) // proper way

#15,0 (white forground, light gray background)

#15,00 (white forground, light gray background) // proper way

I hope this makes sense to you, to be able to edit the IRC_FilterMircColours function ~ Moodles
