I don't think that's what I said at all. If you are reading the file sequentially, you'll always get whatever color comes first, regardless of the order in which you process it.

Or maybe I'm not grasping your question. It seems straight forward, but it is late, and I maybe need some sleep!

Code:
$ cat file
red
green
blue

Code:
for color in line; do
  [ "$color" = red ] && echo "I found red"
  [ "$color" = blue ] && echo "I found blue"
done < file

Code:
I found red
I found blue

Code:
for color in line; do
  [ "$color" = blue ] && echo "I found blue"
  [ "$color" = red ] && echo "I found red"
done < file

Code:
I found red
I found blue

SYNOPSIS

       ppmdither [-dim power] [-red shades] [-green shades] [-blue shades] [ppmfile]

       format suitable for color printers, use -red 2 -green 2 -blue 2.

OPTIONS

       -dim power    The  size of the dithering matrix.  The dithering matrix is a square whose dimension is a power of 2.  power is that power of
                     2.  The default is 4, for a 16 by 16 matrix.

       -red shades   The number of red shades to be used, including black; minimum of 2.

       -green shades The number of green shades to be used, including black; minimum of 2.
