i just finished a bluegill pattern gos as
white basecoat
black along the back and stripe along the sides(i paint three stripes on the sides) not to heavy just so its darker for the next color,
light green shot thru small mesh over the black and on the stripe also the top 2/3rds of the gills Let dry
move the mesh a little and spray gold lightly over the bait leaving about a 3rd of the belly white just behind the bill of the bait(this will be painted orange)
then i mix some yellow with a few drops of red to get orange (just add a drop of red at a time till it looks right)
paint the lower belly orange
cut out a plastic spot for the gill tab holding next to the gills( spray black )
light blue on lower 1/3 of the gills and done
