If we are talking about the shader demo in the qt demos, on my screen,
the color black is adjacent to white, blue and cyan.
Instead, I believe it should be:
colorData=: 1&fc , C=: 0 1 2 2 1 3&{"2 ] 6 4 3$ , CC=:0&".@(-.&',') ;._2 [ 0 : 0
0 0 1
1 0 1
0 1 1
1 1 1
1 0 1
1 0 0
1 1 1
1 1 0
1 0 0
0 0 0
1 1 0
0 1 0
0 0 0

0 1 1
0 0 0
1 0 0
0 0 1
1 0 1
0 1 1
1 1 1
0 1 0
1 1 0
)
Or, more compactly:
colorData=: 1&fc , #: 0&".;._2]0 :0
1 5 3 3 5 7
5 4 7 7 4 6
4 0 6 6 0 2
0 1 2 2 1 3
0 4 1 1 4 5
3 7 2 2 7 6
)
Note also that vertexData could be specified similarly. For example:
vertexData=: 1&fc , _1+2* #: 0&".;._2]0 :0
1 5 3 3 5 7
5 4 7 7 4 6
4 0 6 6 0 2
0 1 2 2 1 3
0 4 1 1 4 5
3 7 2 2 7 6
)
