These are the dye colors that were used. You know that yellow and blue make green. Well the amount of yellow and the amount of blue determine what shade of green you end up with. Brown is made or red, yellow and blue. The red didn't dissolve very well and so there are specks of red all over the brown pieced. So since the red didn't dissolve then there was just the yellow and blue to dye the fabric so it has a green tinge.
Then I did some stuff on my own. These are the dyes that I used for some over dying. I took a piece of cotton that had a light green background and some green leaves printed on it. I used the following colors on some 1/2 yard pieces.
