ALBUQUERQUE, N.M.— KOB 4 Meteorologist Eddie Garcia received a new question for his You Asked 4 It series.


“How do leaves change color in the fall,” Ellery asked.

Eddie said, “During the warmer months, sunshine, itself, powers tiny cells in leaves to create chlorophyll through a process called photosynthesis, this is what makes the leaves look green.”

Eddie explains that other colors hide under the green, such as yellow and orange.

He said we just can’t see those colors because the green is so overpowering.

“As we start getting into the fall, there are fewer hours of daylight and the leaves stop creating the green chlorophyll,” Eddie said.

As the green disappears, the yellow to orange colors become visible.

“Other chemical mixtures can create reddish and purplish colors on some trees,” Eddie said.
