Well, I don't actually design them, it's more like I do the underlying technologies. If you asked me to do any real design, I'd hide under my bed. I'm afraid to try it because I know I don't know anything about design.
With that in mind, I'm trying to learn. Something I just discovered, something obvious to finger-painting five-year-old children, is that colors convey moods. Like this.
I've always gravitated to blues and some greens. I've heard that your color preferences reflect your personality but I'm not sure about that. I'm a big fan of Myers-Briggs personality profiles. I'm a strongly-typed ENFJ and I don't see ENFJ in blues and greens.
ENFJs are idealist organizers, driven to implement their vision of what is best for humanity. They often act as catalysts for human growth because of their ability to see potential in other people and their charisma in persuading others to their ideas. They are focused on values and vision, and are passionate about the possibilities for people.Maybe I just like blues and greens.
