Incorrect colors on C files

[Skepar]

Hello @jonathanchu, thank you for this package.

I have installed and loaded it using use-package. When using it, I have noticed that the syntax highlighting looks different from the One Dark theme from Atom.

On the left I have a freshly installed Atom with some C code opened. On the right I have Emacs with the atom-one-dark-theme loaded, displaying the same code. As you can see, the syntax highlighting is very different.

I am not sure if it's a bug, or if I messed up something installing it... I'd appreciate any help.

Many thanks
