When I interchange rgb for grb I can tell where the biggest numbers in a
viewmat are. Can you using rgb? All I have done here is take each color
triple in thecube pattern viewmat and converted it to its :real countsing
number in the 256^3 position in the more than 16 million numbers. The white
area can be spoted pretty easily.

I think this is what you are asking for:
load 'viewmat'
'E B G C R M Y W'=:#:i.8
V=:<E;E;E
FRONT=:<M;R;W
LEFT=:<M;W;B
TOP=:<W;Y;C
BACK=:<C;G;B
RIGHT=:<G;Y;E
BASE=:<B;E;M
face=: 4 :0
'O X Y'=.y
brush=.D=: <.255*O+"1](%x-1)*((i.x)*/Y-"1 O)+"1/(i.x)*/X-"1 O
)
cube=: 3 :0
plan=: 4 3$V,FRONT,V,LEFT,TOP,V,V,BACK,RIGHT,V,BASE,V
paint=:,/,/>,"_1 each/"1 C=:y face each plan
paint viewmat i.4 3*y
)
cube 5
Personally, I prefer ('rgb' viewmat image), but your approach can certainly
be made to work.
Thanks,
