We all know that color matching is a science, a complicated one, based on eveyrone personal tastes, however, there are some theoretical tools that can help you to choose a color scheme a little more accepted by the general public and, depending on what we are doing, provide a specific sense (or more acurated) to what we want to represent with our graphics/pictures.
This graph I got it by chance today and found it quite interesting, mostly because it explains the feelings that can generate certain color combinations for different cultures. (I know it’s a bit complicated at first and may seem incomprehensible, but if we detail colors from different commercials in our environment we will realize how acurated this graphic can be).
Also, I guess you will find helpful the following tools to create color palettes. Anyway, the idea is to get a base color(s) and generate from there our color palette. Hope you find them useful!
