I have no idea what you are asking. Please try to rephrase the question

Not clear...
Do you mean a column that contains a list of color values (separated by what?) and you want to check that all values are valid color names?
Or do you mean that the column can have one value, picked from a list of color names (lookup table)?

Stuffing multiple values into a single column is an extremely bad design, and the problems you're having querying the data perfectly illustrate why.

Put the valid values in their own table, and set up a many-to-many link between that table and the products. For example:

Colors:

ID   Color
----------
1    Red
2    Purple
...


ProductColors:

ProductID    ColorID
--------------------
1            1
1            2
...
