green yellow orange and red
carotenoids
Several other pigments are found in plants beside chlorophyll. These are: anthocyanin's which reflect red, blue, purple, or magenta colors; carotenoids which reflect yellow, orange, or red and absorb blue light; and phycobilins which are found in algae.
They are red due to the pigment phycoerythrin found in the in the phycobilisomes atached to the thylakoid membrane.
purple The above is the old answer. Mixing blue and red light make magenta, or purple if the blue is stronger. Mixing perfect blue and red pigments makes black. Only if the red leaks some blue and the blue leaks some red will you get a dark purple.
Mixing red and blue pigments makes a purple color. Mixing red and blue light, on the other hand, gives you magenta.
Because it contains the plant pigments anthocyanins, which reflect red wavelengths
it would look red because the light would reflect on the grass ddddddddddddddduhhhh lol jk
Reflect.
blue light and red light make purple light
Blue + red = Purple. Usually the above wrong. It works only if leaky pigments are used. Perfect blue and perfect red pigments mixed together make black. Red and blue lights mixed together make magenta, or purple if the blue is stronger.
Pigments absorb certain colors of light, and reflect others. For example, chlorophyll is the pigment in plants which absorbs red and violet light, and relects green. This is why many plants appear green.
