Read what is RGB to get new colors, or just visit sites providing RGB codes (e.g. http://www.colorpicker.com/ ), choosing color and writing down values of Red Green Blue for your purple.
In your case you seem to lack NameRed color definition. So it will be:
@ NameRed 190 0 0
Some of mine:

# Color name R G B
@ NameGray 173 173 185
@ NameRed 190 0 0
@ NameGreen 0 190 0
@ RedBright 140 0 0
@ GreenBright 0 140 0
@ Green 0 190 0
@ Yellow 250 250 0
@ Orange 254 102 0
@ Blue 70 70 200
@ BlueBright 30 90 220
@ BlueOwn 80 170 220
@ Brown 130 90 30
@ BrownBright 175 120 40
@ Purple 160 15 160
@ PurpleBright 255 75 200

@ Grey 173 173 185
@ LGrey 119 136 153
@ ColdGrey 128 138 135
@ DRed 120 0 0
@ Mint 189 252 201
@ PurpleDark 128 0 128
@ Magenta 205 0 205
@ LGrean 113 198 113
@ SeaGreen 46 139 87
@ Cobalt 61 89 171
@ PinkRed 205 92 92
@ LRed 254 50 50
# Then you can use same RGB e,g, for factions:
@ cBlueGeckos 0 190 0
@ cAotN 113 198 113
@ cRandoms 46 139 87
@ cKotW 113 198 113
@ cPist 113 198 113
@ cOrganized 113 198 113
#Then start colorizing characters, e.g.
# My Characters
> Phoenix Orange
...
# Blue Geckos
> Gifted?Crafter cBlueGeckos
...
# Randoms
> Lieut.Doon cRandoms
...
# Betrayers
> Matze Yellow
...
So it should look like this?
