Illegible syntax on code snippets.

Heya there. I was just doing some research on graphql clients and stumbled upon relay. Whilst reading the landing page I noticed that the code snippets advertised are incredibly hard to read due to the poor choice of colors for the syntax.


As you can see from the CSS Overview in the browser's devtools, the contrast is terrible in terms of readability. I suggest a change in colors for better readability. (Also this is my very first issue ever on github 😇).
