Question:
How can I make the chlorophyll in
grass lighten up so the grass will change from green to yellow or orange?

Belita,
An interesting question....designer lawns :)
I do not have specific data available, so you might
want to research this a bit further.
The color change we see in leaves occurs due to
partial resorption of chlorophyll with the arrival of
cold and short days in the fall. With the chlorophyll
gone, the other pigments present in the leaves become
visible.
My lawn typically goes from green directly to brown.
Because of this, my suspicion is that the pigments
present in leaves which create the vibrant color we
see are not present to a great enough extent to create
the same phenomenon in a lawn. This, however is just
a suspicion.
You might check for articles on research into grasses
or contact your local county extension agency for a
contact regarding lawn research. In the research you
want to check if other pigments are present in the
normal blade of grass.
Good luck!

You could try covering it with burlap or shade, then the grass will yellow.
