What color would a star be above 30000 feet?

At altitudes above 30,000 feet, the color of a star would still appear similar to how we see it from the ground, primarily due to the lack of substantial atmospheric interference at that height. However, the thinner atmosphere may enhance visibility, making stars appear brighter and their colors more distinct. For example, blue stars might appear even bluer, while red stars could stand out more vividly. Overall, the color perceived would depend on the star's inherent characteristics and the observer's visual acuity.
