After looking at these designs for a while some of the colors look "neon" to me. I like the flat color in #53. I'm thinking that using green might not look good with all the green I have in the site.
http://homeserverpodcast.com/ is the reference site.
I am open to your color interpretation for the design. I still think a blue would stand out, perhaps a maroon like what is in the example logo on the site. The color list is in the brief and green was the first stated color so maybe that's why I see so much green! If you have thoughts on the colors PM me and I will listen. You are the professional.
I have recently ranked the designs so I hope that helps you see what I am liking better.
#59 and #59 have potential but i do like a design with the text better. Feel free to move the text around, rotate, etc.
