Degree Project progress

I am trying to come up with a basic look and feel to the brand of my website. I want the colors to be very calm and inviting. I am also focusing on how you can categorize these colors and put them into groups. For example are the blue ones a photo, yellow a video, and pink just a text based experience? And maybe there are tags to the stories and once you enter them the dots cluster together to match your tags? The ripples around the circles represent the interaction of users. The more a story is liked or commented on the larger the circle grows. I am playing around with names but have not come up with anything yet. I want something to relate to the idea of growing together, embracing each other, sharing, ect.
