It amazes me how easily we adapt and respond to visuals. Not only is functionality important to software development, but design is also pretty important. Because time is a limited commodity, usability and intuition are important factors when encouraging users to adopt a new system. And generally, the visual elements of the system determine how quickly users are able to learn a new application. Design includes many different aspects – color, layout, fonts, sizes, etc. You have to be strategic with your design elements, including those micro-images we call icons. Those seemingly small symbols ultimately make a big impact on user navigability and comprehension.
Who else but Google has created a style guide for all of their applications and shared it on the interwebs for everyone to use. Material Design is basically a design language that Google created to unify digital interfaces and experiences. They offer lots of good UI/UX design ideas in this document and a bunch of free resources. Who doesn’t like free stuff? One of those free things is a whole set of icons, nice ones.
