What you could do is put a Vlookup chart on another sheet.
Suppose that you have this in Sheet2!A1:B5
Code Explaination
Be blue
Bk black
Br brown
Gr green
Gy grey
then if "Gr" were in Sheet1!C1 then the formula
=VLOOKUP(C1, Sheet2!$A$1:$B5, 2 ,False) would return "Green" to the cell that held the formula.
Lists like this tend to change and formula need adjusting (probably in about 3 months).
Using techniques that one is familiar with makes that maintenance easier.
