Color of texts on bars (defined by VALUES and LABELS):

The color (black/white) can be determined automatically by
[autom_color(x)] where 0<=x<=1 (typically x=0.5).
Thus when the background (shading) is light, texts are black
and when the background is dark, texts appear in white.
These colors may be also set individually, see COLORN?
