No. We have discussed this so often in the past. We use for good reason not white. Black/white tires your eyes more than using black/light yellow that we use. In a lecture at the University I also heard that this was the result of medical studies. Personally, that is also my experience.
Besides this, we also already discussed the whole coloring scheme in early summer this year and decided to use the current one.
