[BioC] greenred.colors() in geneplotter

[michael watson (IAH-C)]

OK, so why:

> greenred.colors(11)
 [1] "#00FF00" "#00D100" "#00A300" "#007400" "#004600" "#001800"
"#180000"
 [8] "#460000" "#740000" "#A30000" "#D10000" "#FF0000"
> length(greenred.colors(11))
[1] 12

?? :-)

greenred.colors(10)
  [1] "#00FF00" "#00CC00" "#009900" "#006700" "#003400" "#000000" 
"#330000" "#670000" "#990000" "#CC0000"
[11] "#FF0000"

#000000 == black, which technically is not a green or red color, but 
which is necessary to indicate no difference.
