Haha yeah, I think red might cause some angry emotions for sure :) it can work for some companies, but I'm not sure it's a great fit for Gridcoin. I'll work up some options for the next post and see what people think! I do also like the aqua blue - fortunately, the versatility of the logo and the decentralised nature of the community mean that if an individual user prefers one colour to another they could easily change it for their personal preference :)
Thanks for the feedback!
