What is the different
between a concrete logo and abstract logo?
A concrete logo uses figurative or symbolic objects that you can easily recognize: pencil, envelope, bag, dog, or anything else you’ve already seen in your life.
Therefore, your brain will easily recognize what you are seeing and if one of these objects appear on a logo, you will immediately have an idea of which industry this business belongs. All the process to remember this logo is much simpler and very fast.
An abstract logo is exactly the opposite, it is very hard for our brain because there is nothing we can compare with our memory. Therefore, we need to make more efforts to understand and remember it and to connect it because our time and attention are needed so much in our daily life. You can assume how much people really make an effort to remember an abstract logo.
