Absolutely. Why the seasonal change? Algae (Both "green" and "brown") changes the water clarity and the location of bait. Algae grows expotenially (Spell check) as the spring becomes summer. It really makes a huge difference. You also find fish deeper in summer temps so your lure colors will tend to change with those deeper depths. I hope I answered your question completely but let me know if not. Blessings, -TJ
