@Don Cragun: good approach, but I had to modify it slightly to make it run on my linux host, like:


Code:
printf '%s\n' "${array[@]}" | while IFS== read -r color sequence
  do    printf '\e[%sm%s\e[m\n' "$sequence" "$color"
   done

(print just one array element at a time, and split the line read at the = sign.)




EDIT: I have to apologize; my fault when creating array. Don Cragun's code works flawlessly if array is defined the way he did in his post, with an element pair per colour entry.

       colors	       Pointer to colors multi-component row. colors must be 8-byte aligned.

       n	       Length of color1, color2, and color3 arrays. Length of colors must be 3*n.
