Question

why is a leaf red orange blue violet​

Answer 1

Explanation:

Xanthophylls are yellow pigments, and carotenoids give leaves an orange color. Photosynthesis also uses these pigments during the summer, but chlorophyll, a stronger pigment, overpowers them. These pigments take more time to break down than chlorophyll does, so you see them become visible in fall leaves

Answer 2

${\Huge{\fcolorbox{orange}{ORANGE}{Answer}}}$

Plants (and animals that eat plants) can then store the energy and get it back out when they need it by breaking those chemical bonds. ... Other pigments that plants have in their leaves absorb light of different colors, so they reflect red, orange, yellow, or blue light and appear to be those colors to our eyes.
