Create simple syntax

Hey, I don’t really understand how github works, however I would like to make my own theme, I was a full python idea before; I keep the references of my “syntax color” as an example of what I would like to do

class name = # 33FF00
how = # 0066FF
Number # FF0000
Function = # FFCC33
no reserverd KeyWorld = FF00FF
system function and var = FF33CC
string = # 009900

Is it possible to reproduce it in syntax? I really did not understand anything in the tutorial so I come to ask for help … thank you very much * ^ *
