About the sunflower's color
Kansas chose the sunflower in 1903 — the same state that today produces 40% of the world's sunflower seed. Young sunflower heads track the sun across the sky (heliotropism), then lock east when mature. In ToonTone Guess, we represent the sunflower with the hex value #FFC107 — the color most people see when they picture the bloom in a vase or in a field.
