Science & Environmental Facts : Why Does Chlorophyll Appear Green?

Chlorophyll appears green because the mixture of colors in light reflect only the green color in chlorophyll and absorb the other colors. Find out how the spectrum of colors in white light creates different colors with information from a math and science teacher in this free video science lesson.

Bravo, Steve, thanks for the Patronizing science lesson. .....Ok, ok my 3 year old nephew and I understand the fact that the leaf reflects the green light (not sure you needed to demonstrat all three colors; I think i got it after blue!) but why does chlorophyll reflect the green light when its the most abundant in the spectrum...What in the evolutionary process was beneficial about discarding green..Thats the real question you condescending ignoramus

Good explanation! This video is probably the best explanation of the color of chlorophyll (in the summer).

[robair21]

When a leaf has changed colour in the fall, it is because it is dying and thus is loosing its chlorophyll. This is why the appearance of leaves in the fall tend to be a reddish/brownish colour because instead of the green being reflected, the green now becomes increasingly absorbed and the red and blue increase in reflectance.

It will not be correct in assuming the actual colour of a leaf during the fall season, as it is dying at this stage.

Question...

Considering that chlorophyll makes a leaf green, then when a leaf turns a color in the fall, I assume that it's the absence of chlorophyll, right??

So may I assume that the ACTUAL color of a leaf is the color that it is in the fall (autumn)?
