If you've already decided on the dubbing color, go ahead and color the Mylar with a matching ink pen. Create small ball-shaped eyes on a length of stiff monofilament by grazing the tips with a butane or alcohol flame. The mono will melt rapidly, leaving a ball-shaped bulge on the tip. Dip the tips in black vinyl jig paint and set aside to dry. Wrap the entire hook shank, ending at the bend.
Color is optional, but keep it life-like.
I like to mix two colors of dubbing material, but you can use a single color, too. The trick with dubbing is not to put on too much at once and to spin the thread in the opposite direction after every dubbing application. Alternatively, you may use a sparkle yarn. When you color the shell, make sure to color the sides, as well the underside. Lay a thick bead of a super glue on top of the shank and glue down the foam shell so that the end of the tail meets the end of the hook eye.
