315 = 255
90 = 0
Between the two you have 135 degrees (45 from 315 to 360 plus 90 from 1
to 90). 45 / 135 = 1/3, so 360 is at 255 - 255/3 = 170.
Obviously this means that you go from 255 to 0 much quicker when you
move

Also, it usually helps to do a histogram equalization on each band prior to
compositing. i.landsat.rgb does some of this kind of enhancement automatically.

I'm using some Ordnance Survey street-level Mastermap data which

I can produce basic map labels using v.label:

I tried shifting the interpolation method. Nothing worked. When I try to
change the color rules, in 6.4.1 it runs the change, but doesn't add any color.
When I try in 7.0 svn, it grays the apply and okay button.

There is no reason to use 'sync' or an equivalent. sync causes
