In The Green is where I'll be

In the green is where i'll be.
Not in the grey,
For no hope clouds the day.
Not in beige,
Who wants to work anyway?
The green helps me go my way.
The white,
Gives me too much might.
The rainbows,
Turn my eyes to toast.
The liquid brown,
Will make me drown.
Only green has means to make me be.
So use the yellow to make you mellow.
Your day may remain grey,
And with that, your hold on life will fray.
My hold on life shall never change,
For in the green is where i'll stay.
