I'm confused by your description of what you want. Your data/report looks like this:
Group Panel Value Mean
111 c 11.11 22.22 <---pink
111 c 12.12 21.21 <---pink
111 b 13.13 13.45 <---yellow
222 a 45.45 56.56 <--- what color for these???
222 d 77.77 77.77
222 d 88.55 66.66
Are you saying that for group 111, when panel = c you want one color??? And then for Group=111 and panel=b, you want a different color??
And then WHAT do you want to color??? the panel cell??? You want to color the group cell and the panel cell??? Or you want to color the whole row???
Also, you indicate that you are using ODS to create a file that Excel can open...but are you using:
And, also, what is your procedure of choice?? Are you using PROC PRINT, PROC REPORT, PROC TABULATE?????
