Using historical weather reports, tree species info and user data, travel brand SmokyMountains.com put together the map for the entire country.
Between the lines: The green color in leaves comes from chlorophyll, the pigment that helps plants turn sunlight into energy via photosynthesis.
As nights get longer and days shorter in the fall, leaves stop making chlorophyll. The green color fades and the yellows, oranges, reds or purples become visible.
The bottom line: Rain earlier this year, warm weather and sunshine should help the colors overall, but THV11 warns the drought could be the wild card that may mute some colors.
