The famous nocturnal Hex hatch of the Midwest (and a few other lucky locations) stirs to the surface mythically large brown trout that only touch streamers for the rest of the year.
if you find it important to imitate this feature, the best way is to use a neutral thread to tie the fly and "paint" 3 inches or so of it with the proper colored marker for finishing off the head
I have to admit that coloring the head to match eyes has never proved to be all that significant in my years of fooling around with fly patterns.

I tie "eyes" a little less complicated than this.
As I start to form the head with my regular "fly" thread, I tie in the "eye" color thread with three wraps of the "fly" thread and then a three turn whip finish with the "fly" thread and cut the "fly" thread.
Then I tie in the new head over that with the "eye" thread and make the desired size eyes, followed by a five turn whip finish. Takes about fifteen seconds.
There have been many occasions where an orange head PMD out fishes a regular one, or I slayed them on red head Sulfur when nothing else worked...
