Do you mean larger in regards to what is currently on http://egobits1.github.io/ or what you may see in @elioqoshi's suggestion?
Sure, in general we can and should play arround a bit with the color squeme employed and then decide on a final draft.
Sure, like I've said before, testing a bit until we find a sweet spot is probably a good approach.
Like @Patrick said, the wording will be improved once a visual base has been created.
Have a nice day,
