I dyed a cream one, I used olive green, it didn't take well so I then used forest brown. It came out a decent colour but a bit on the light side. If I did it again I'd skip the machine wash dye and use hand dye and give it a good long soak and use a dye darker than what I want to achieve...This is just my experience, I'm sure others have had better results. you can get some crazy colours with natural dyes but that's beyond me!
