I think you want:
load 'viewmat'
(,:0 0 255) viewmat 0
(,:0 255 0) viewmat 0
(,:0 255 255) viewmat 0
(,:255 0 0) viewmat 0
(,:255 0 255) viewmat 0
(,:255 255 0) viewmat 0
To see why compare:
0 { 0 0 255
0
and:
0 {,:0 0 255
0 0 255
You can try that with the other left arguments for viewmat, if you like.
Thanks,
