I have something like that with numbers but not colours. I see the numbers unfold as a pattern in my minds eye. Kinda like this

                                       
                                        30 30 31 32 33 34 36 37 38 etc
                                       29                      40
                                     28                      41
                                     27                      42
                                    26                      43
                                  25                      44
                                  24                      45
                                 23                      46
                               22                      47
                               21                      48
                                                       49
10 11 12 13 14 15 16 17 18 19 20                      50

They don't always go in the direction you'd assume. I just see them this way and have every since I was a kid. I can draw the pattern out all the way up through the thousands. The pattern starts to repeat itself at times but not always. Anyone else.

I wonder if this post will show the pattern properly.
