I enjoy this hibiscus. It's blooms fade throughout the day. The blooms usually start out bright orange. By mid afternoon they turn dim orange or sometimes have a dim yellowish appeal. By evening pale yellow to whitish. If memory serves correctly, I've noticed they go through their color change quicker on sunnier days. On overcast days their bright orange color lingers longer. A very interesting hibiscus.
