Here are some of my proposals. Instead of creating a separate icon / typography combination, I've created an all encompassing logo / unit. One that can be used for additional elements just as watermarks.
The logo is 100% vector so will scale well to any size, and works well in full colour, B&W and on coloured backgrounds if needed,
It would be my pleasure to work up any variations so please do say. I look forward to your comments or thoughts.
Angus, I like the modern feel to your logos. Please remove the CTA from the C and show me another version with green so I can compare it to the blue version. Thanks
Angus, after seeing many entries now, I favor the copper/blue combination over the copper/green one. I'm leaning more toward the copper on black, which really stands out. Do you have any suggestions with this color scheme?
Just wanted to show, with #187, that it will still work on a light background as well. Often clients will use multiple versions to cover all possible situations i.e. one for dark backgrounds, one for white backgrounds and also B&W versions for possible newspaper or single colour printing.
