pink skies about is/are often referred to in the context of weather folklore and the saying “Red sky at night, sailor’s delight. Red sky in morning, sailor’s warning.” This phrase suggests that a red or pink sky at sunset is an indication of good weather to come, while a red or pink sky in the morning could signal that bad weather is on the way. The explanation for this is based on the way that light is scattered by particles in the atmosphere under certain weather conditions. However, “pink skies about” is not a common standalone phrase, so if it has a different specific meaning or reference outside of this context, then no_definition.
