Other than by painting it yellow, all you have to do is cover it up, and the green chlorophyll pigment will fade. Grass under temporary Swimming Pools usually turns yellow and may begin to ferment (rot).
Grass that stores its pigment during the winter usually turns brown (tan) rather than yellow.
wWhy wouldn’t the grass be green?
The grass turns green when it is exposed to sunlight.
A dull mower blade will "tear" the grass instead of "cut" it. The jagged blades of grass will dry up and cause your lawn to look brownish or even yellowish - much like when cut grass clippings turn from green to brown/yellow as they dry up.
If a black sheet of plastic is laid on the grass, the grass will turn yellow because the the starch produced in the grass gets consumed up . since no sunlight is available to the plant to produce more starch,it will gradually start turning yellow. ;-) ---------------------- The loss of green coloration equals the loss of chlorophylls, which is the result of the plant putting chlorophylls in storage when sun light is absent.
Well, the grass is green because the sky is blue and the sun is yellow so mix them together and you get GREEN!!!
no there pee is just kind of just a lime green.
Look after it more and water it
Grass is always a healthy green when, well, healthy. When dying from lack of water, CO2, etc., it will turn orange, yellow, etc.
Green if it is the grass and yellow grass if it is dehydrated. Brown if its muddy
