There are a few things to know about how to use the colour scheme. Again, basic shit but gotta make sure you know it. Each section of the app has its own designated colour that the page should be based around. Due to this there is no real main colour of the app.

The kind of idea I'm going for is having it identified by those 5 colours in that specific order. The HTML colour codes are listed at the bottom of this along with their use. You'll notice 3 extra colours at the bottom; white, green and black. They can be used anywhere but I do ask that if you use black it is only as a border or text colour. Large boxes of black tend to be disgusting.
But of course all this is specific to the actual app, for the landing page you are pretty much free to do whatever you want. Feel free to use the screenshots from the dropbox link in the overview I sent originally. If you want any of the other features from it exported and sent to you as an image feel free to ask.
Fonts are something I'm pretty pissy about. Montserrat is what I've been using for most the stuff so far.

The C from the logo is I think in it too but don't quote me on that. Other fonts I'd like you to use include Roboto and the such but in the end, just pick whatever you think fits the best.
For what to put on it as a landing page I have a few things I definitely want on there and then it's your choice whether to expand on that or keep it as is. Stuff you need is; link to iOS download that pops up a little coming soon page, link to android download that has the same coming soon page, a page for contact details (I'll give you the email to put there once I've set up the domain DNS) and a page for the press kit (effectively just a bunch of images I'll give you that can be used for promotional shit. https://en.facebookbrand.com/assets That's kind of an example but with a lot less stuff and much less complicated, all you'd have is a couple of logo variants, a banner, a background and the colours). Add whatever else you can to make it not feel so empty.
I know it's quite a lot to ask so if you want to do anything differently just say and I'll see what I can do. For this part you'll just get a very basic ftp server that'll be hosted with 1and1. I'll migrate this over to an EC2 instance at a later date. Once you need to start doing proper backend scripts for a web app or if you start working on one of the other areas I'll either give you access to the correct instance for that job or make you a new one that you can use however you want.
This is pretty easy, shouldn't take you too long. Again, I'll set you up with something worth your time after this is done. There's just quite a few things right now that I need done before I can move the my full attention into the app, doing this will save me a lot of time so thanks in advance. I've told the other guy that I'm not doing payments until launch, at that point if we can get a few members you'll be compensated for your time in both equity and cash.
