There is no definitive answer to this question since it ultimately depends on personal preference. However, some people may find that a light patio umbrella is preferable because it can help reflect heat and keep the area cooler. Additionally, a light colored umbrella may be less likely to absorb heat from the sun, making it more comfortable to sit beneath. On the other hand, a dark patio umbrella can provide more shade and may be better at blocking out the sun's rays. Ultimately, it is up to the individual to decide which type of umbrella is best for their needs.
