+# A simple test of your console capacity to present so many colors is:
+# for r in {200..255..5}; do fb=4;g=1;b=1;printf '\e[0;%s8;2;%s;%s;%sm   ' "$fb" "$r" "$g" "$b"; done; echo
+# It will present a red line with a very small change in tone from left to right.
+# If that small change is visible, your console is capable of 16 million colors.
+# If your console type support this, this code will create a color table:
