 [color:green] 
if ($did($dname,40).seltext = $null) { did -d $dname $did 0 | did -u $dname $did | halt }
      if ($did($dname,$did).seltext = White) { color $did($dname,40).seltext 0 }
      if ($did($dname,$did).seltext = Black) { color $did($dname,40).seltext 1 }
      if ($did($dname,$did).seltext = Dark Blue) { color $did($dname,40).seltext 2 }
      if ($did($dname,$did).seltext = Green) { color $did($dname,40).seltext 3 }
      if ($did($dname,$did).seltext = Red) { color $did($dname,40).seltext 4 }
      if ($did($dname,$did).seltext = Brown) { color $did($dname,40).seltext 5 }
      if ($did($dname,$did).seltext = Purple) { color $did($dname,40).seltext 6 }
      if ($did($dname,$did).seltext = Orange) { color $did($dname,40).seltext 7 }
      if ($did($dname,$did).seltext = Yellow) { color $did($dname,40).seltext 8 }
      if ($did($dname,$did).seltext = Light Green) { color $did($dname,40).seltext 9 }
      if ($did($dname,$did).seltext = Teal) { color $did($dname,40).seltext 10 }
      if ($did($dname,$did).seltext = Light Blue) { color $did($dname,40).seltext 11 }
      if ($did($dname,$did).seltext = Blue) { color $did($dname,40).seltext 12 }
      if ($did($dname,$did).seltext = Violet) { color $did($dname,40).seltext 13 }
      if ($did($dname,$did).seltext = Grey) { color $did($dname,40).seltext 14 }
      if ($did($dname,$did).seltext = Light Grey) { color $did($dname,40).seltext 15 }
 [/color]

[/color]
basically it boils down to:
color red option [color:green] colorcode
