Hi,
Thanks you very much for your question. I really appreciate it.
As you mentioned on the brief, that you want something that express sophistication, wisdom, imagination, knowledge, trustworthy, perfection, purity, wealth. Based on that points, I believe that the blue color is the perfect color to used. It would also practically have a good cost when it produced in any marketing material such as on business card, letterhead, brochures, signage etc, without loosing any points that you want to be communicated through this logo.
Also, most of the great brand/logo were using a simple elements including on the coloring used. But of course I would be gladly try to propose some color option for your consideration.
I hope this short presentation would helps.
Please don't hesitate to let me know if you have any request or question.
Best regards,
Ruri
