I would like the logo to evoke an emotion of empowerment. Images of Humanity or Nature - ie. beaming light from within or thru the clouds, ripples from a stone in still water, etc.
It should be an image that makes a person feel "Inspired"; something that reminds them of how special they are; ...that your just being here makes a difference. You, just being you, is constantly IMPACTING the world around you.
My business is designed in-part to inspire people to be conscious of the IMPACT they ARE on the world around them and to use the IMPACT they ARE wisely. They change the world by just BEING here.
I really like logos that are simple and effective; that communicate volumes with very little.
The most important element for me here is EMOTION. I want to feel something when I look at it. This is best done using images/shapes/designs that have universal meaning and significance-something we all relate to as human beings.
As for color, please feel free to be creative. Simpler is better.
