Every 2.2 years, the planet's orbit takes it between a Venus-like distance of 0.6 AUs to a distance of 2.7 AUs, further than Mars. This means that the planet undergoes extreme differences in temperature throughout its year. How this would effect a Jovian world is unclear. No major seasonal changes have been recorded on any of the four Jovians of our own solar system. It is known, however, that temperature does seem to effect color variations in the clouds of Jupiter.
High clouds tend to be darker, where low clouds are lighter colored.
The altitude of a cloud layer effects its temperature, with high clouds being cooler. Also, the planet Saturn, sitting in a cooler orbit than Jupiter has more upper atmosphere haze, giving it a more smooth appearance than the churning clouds of Jupiter. One may imagine 16 Cygni B b changin appearence as it traverses its orbit. Close in, the planet would be relatively bright, with warmed white clouds. Further out, the planet would darken and become more hazy as temperatures drop.
