Why did the color of the Bromthymol Blue (BTB) solution change in certain test tubes?

if the bromthymol blue changed back to blue from a different color that means that different atoms of another element were in the air. if you tested the bb in a test tube and say it was turned yellow and then overnight it turned back to blue-green then it would mean that a certain amount of oxygen went into the test tube to reverse the change. if there was lots of oxygen in the air then the bb would turn completely blue since bb is not really blue but a weird green color.
