Semi Colon vs Colon question?

I humbly disagree with Anna. The colon is correct in this case. The use of a semi-colon would be correct if what followed was a complete sentence related to the first, however it is not. Yes, the colon is commonly used when followed by a list, however it can also be used here. Think of the test for a colon as replacing the word 'namely' or 'such as'.
