We are not set on specific colors, but avoid red and blue because they indicate Republican or Democrat. Purple is a good color because it suggests both Republican and Democrat acting or bipartisanship. Green is also good because this is an environmental initiative. This is a professional service, not consumer-oriented.
Our Ideas and Additional Information:
We bring people together around a table--so a logo that depicted this in some way might work. This could be abstract.
We work on climate change and clean energy but the logo is probably better focused on the collaboration and working together theme.
We are also attaching a map that shows our network, but it's too busy for a logo--but maybe there is a more abstract way of depicting this? Providing in case it gives inspiration but not necessary to use map concept.
