I've been developing only responsive websites now for over a year, and it is becoming more and more important these days. There are a lot of reasons to go responsive, and there is a lot of design and UX/UI thought that needs to go in to it.
Creating colour palettes for site design is fun (at least for me that is). But getting the right colour combination can be very challenging. Enter Color Scheme Designer. A free, fun and visual colour palette creator that will make creating colour palettes a cinch.
Ever had trouble trying to explain to a client what responsive design is, and how the content flows between different device sizes. Unless your there in person, it can get tough, e.g.: over email or on the phone. This awesome little interactive simulator from Fine Citizens will help any client visually understand what a responsive site is.
