"Positive" vibe – theme

I’m in the look for a WP theme (premium or free, doesn’t matter) that has a positive, happiness, motivational vibe to it. So no dark colors, not too minimalistic. Can be responsive, magazine or whatever.

The site would have/post videos, quotes (although there are lots of widgets for quotes), stories/articles and a place where users could submit their own stories and other users can rate it. Nevermind the features, the theme doesn’t have to include all of them. So a portfolio theme is out of the question.

I tried searching for Kids themes but they are too rich in colors, although the theme should have bright colors. And given those features (probably will have more), should I look for magazine themes or what? Which websites/theme creators would you recommend I check out? WPExplorer, WooThemes…?
