Color usage documentation #82
Description
Hi @junegunn,
What do you think about adding documentation on how the colors are chosen for the parts of the code that they highlight.
Looking in the code I could only find the numbers from 1-255, making it hard to implement the color scheme for other applications.
For example I created sharkdp/vivid#93 but figuring out the colors was difficult.
A simple table in markdown in the Readme could be enough and help to establish the Seoul colors across many apps.
