Update figma per client feedback

[HuxleyBerry]

Overall, the client really liked the figma designs we made. However, there are a few things we need to change:

• The client is actually comprised of two different organisations: Blue Crew and Ocean Youth. At present, the figma only uses the branding colours from Blue Crew. Ocean Youth has a green/teal colour they would like to also be used (see the figma). So we need to find a way of incorporating that colour.
• The client commented that the beige colour we've been using makes the website feel a bit "adulty". This is not ideal since the target audience is young people. Maybe we can find a way of reducing the usage of this beige colour.
• The name of the game is change from "Blue Crew Bingo" to "blingo"

In the future, we might need to change the logo we're using, but we can leave it for now.

Instead of modifying the current designs, please make a copy of them and edit the copies instead. These can all be in the same figma document -- we can have two headers: "Old Designs" and "New Designs". It's not necessary to edit every single design -- just enough that we get the idea of the changes that would be made to all of the designs.
