 Due to security concerns you cannot call FetchSpecifications from the client-side that use a Raw SQL Expression without implementing the delegate method distributionContextShouldFetchObjectsWithFetchSpecification which this code does NOT do.

If you try to, you will get the following exception in the server log:

Unknown macro: color. Click on this message for details.

and this code will return null to the client instead of the expected FetchSpecification.
