Potential Colour Pallet

After looking at other magazines i have seen that most magazines have a base 3 colour pallet. This usually seems to include black, white and some bright colour that is used to grab the readers attention by really standing out. Because i want a dirty and earth feel to my magazine i decided to do this, but with a slightly darker green colour, as shown below. I believe a green colour with give it the earthy feel that i want. However the green shown may change to a slightly darker one, pending on tests.
