Thanks, Cameron.
Unless we get any other submissions, I've got a Google Form ready to go to ask for preferences on this that I'll send out tomorrow morning. It includes the montages and color space diagrams; they can all be viewed here: https://drive.google.com/open?id=0B1DaRHnSGW8Za0U4cEFTTzVPcVE

Sounds good, but before we do that, I think we should have a suitable waiting period for others to propose them. I'll send an email out to yt-users asking for ideas on it.

I think we should probably put it up for a vote and we should send an e-mail to yt-users about it.

Hi folks,
I've put up a comparison image:

Left is Kacper, middle is me, right is Nathan.
Honestly I think all could go in, but we should pick a default -- whether it's one of these or a different one. Anyone have a strong opinion?

Wow, all of these look great. I think I like Matt's best for painting our bikeshed, but I would be happy with any of them.
