Kelly,
You will find the CIELAB equation you are looking for in
the following pdf:
http://www.babelcolor.com/download/BabelColor_Help.pdf
Look in the
Technical data/Definitions and theory/DeltaE
section.
The formula can be used almost directly in Excel.
Essentially, it is:
= SQRT((L1 - L2)^2 + (a1 - a2)^2 + (b1 - b2)^2)
where L1, L2, a1, a2, b1 and b2 should be replaced by the
cells references where the data resides.
