Let me first explain the title. During summer 2016, I went to a conference on string theory and derived categories where it was remarked physicists always use more creative adjectives (e.g. ghost numbers). For me, mathematics is the embodiment of creativity. Over the years I started to associate symbols with colors, hence the term colorful algebra. Examples of colorful objects: $\mathbb{C}$ is yellow, $\mathbb{A}$ is orange, $\mathbb{P}$ is purple, $K$ groups are green, $\mathbb{Z}$ is white and it gives rise to a spectrum of colorful fields, $\mathbb{F}_2$ is cyan, $\mathbb{F}_3$ is also yellow, $\mathbb{F}_5$ is red.
