(Ignore the traces of very bright green that's Vallejo Model Air 71007 Olive Green)

I wanted it more like this....

Maybe a wee bit darker. Any suggestions for a better colour?
I thought at first I had got the XF61 mix contaminated so I mixed up another batch.
I wonder if paint can go off. It is an old jar.
It's goes onto a light grey primed base as sewer brown and darkens to a very dark OD after heavy spraying.
