I like the way you higlighted specific cells but made the resolution of the picture low enough that you can't actually see the numbers. Nice touch, that.
I was being sarcastic. You could apply the colour thing to any set of numbers so it doesn't really matter. It looks like this is for 5x31. It doesn't really add any new information aside from highlighting (-1,n). We were already told to do that, but when I looked into (-1,n) I didn't find any unique patterns that changed anything, and it had the same patterns as the other negative square columns ((-4,n), (-9,n), etc). We were already told to do that colour diagram thing too, early last year. He said that the colours were significant. The only other time he used these same colours was in his triangle diagrams, but I don't remember being able to find any useful connections personally (plus nobody found anything originally (GA made some example diagrams but I don't remember which thread this was)).
