The logo SHOULD be:
Clear, concise, clever, modern, and high-end.
I am indifferent about the use of colors. This may change once I start to see submissions, but as of right now, the sky is the limit.
Also, the logo should focus on "Gerendum." The "Estate Management" part can or can't be used as part of the logo. Use the option to your benefit. Again, my position on this may change, but will ultimately be informed by the responses.
Also, a real subtle use of Gem imagery in the white space would be really cool (and clever). Again, I don't want this to be the focus of the logo necessarily, but think it would kind of be like the arrow in FedEx... One of those things that you're sure to miss if you don't know what to look for...
The logo should NOT be:
Look like its from 1999
More "NOTs" to be determined as submissions are entered.
Should not incorporate or make reference to geographical variables.
Have fun with this! We are a fun company run by a young team so we are receptive to a lot of different creativity! Also, feel free to ask additional questions. We will be monitoring the design process closely and will provide ample feedback. :-)
