Well... actually, there is another way. And the red was a hint about that other way.
To see the other way, try this: load 'viewmat' (256#.0 0 255) viewmat 0 (256#.0 255 0) viewmat 0 (256#.0 255 255) viewmat 0 (256#.255 0 0) viewmat 0 (256#.255 0 255) viewmat 0 (256#.255 255 0) viewmat 0 Do you think we should keep this a secret?
