The example by Christophe seems to be correct.

I show below results of my experiment (by using MetaPost 0.641).

[1] change of dvitomp
max_color_stack_depth = 11
  color stack overflow occurs
max_color_stack_depth = 12
  There is no error. Resulting EssaiNew.1 is OK.

[2] consistency of the example
mpto -tex mptextmp.mp >mptextmp.tex
latex mptextmp.tex
dvitype mptextmp.dvi >mptextmp.txt

The file mptextmp.txt shows:

Number of 'color push' command = 16
Number of 'color pop'  command = 16

I attach the file mptextmp.txt.

Best,
Akira
