Find Mismatched Cell Values

I am trying to identify cells within a row that have a different value from the second cell in the row. (The first cell in the row represents the identifier) All the cells within the row should either have a blank (if there was no value linked to the identifier) or a set of RGB values separated by commas. I have tried a variety of MATCH, EXACT, Special - duplicate rows, type formulas but either the commas within the cells or the blanks are messing with the formulas. Please let me know if I need to clarify more. I have attached an example of my spreadsheet. (As you can see in row 2, J2 and K2 are different from B2, so ideally I would like these cells to be highlighted to point out the difference). Thank you in advance to whoever can help.

Thank you so much!!! This did the trick. I was about reply asking how to exclude blanks and sktneer solved that for me.This has really helped! Just a note for anyone who may read this later, the first time I applied the conditioning I accidently included column B in my range (B2:L19 instead of C2:L19) and it gave a partial output of what I wanted and I couldn't figure out why it wasn't working. So that was a easy fix once I realized what I had done.
