Well, I still think you should add a final option of "none of the above" (please)
I do understand what you are trying to do, and I have read all the posts.
With respect to the royal blue. Reread my original post. I was NOT necessarily proposing it, just giving an example. I was just suggesting that using different shades of red and/or blue, MIGHT be better than white, and MIGHT be a way of reducing clashes, and MIGHT be a different approach to the problem.
Just trying to use a bit of lateral thinking, we're not necessarily on different pages!
