The red color of the interface of the site is making eye tired, maybe change another color is much better.
Isn't there a button on chainroll to change the color? Perhaps I'm remembering wrong but I thought they had night/day modes. Even if they don't, you can always just change the color of the background with javascript in your browser:
document.getElementById("idofthedifyouwannachangethebackgroundof").style.background.color="white";
