Colour Schemes

I am unsure of where to go with my colour schemes, as I have not been given a direction for them as of yet. These are three different ones I have come up with that I can experiment with on my site layouts

They all have grey in the as I thought it would work well for a background colour, although all of these colours schemes can be changed at this point as I am still unsure of where to go with them until the client looks at them. For now, I am sticking with the bottom colour scheme as I can experiment with all of the different colours in it.
