The sentence that shows the proper way to use a colon is: Van Gogh painted my two favorite pieces: Starry Night and Sunflowers. The punctuation mark, colon (:) is generally used when introducing a list. But a certain rule is applied when using this punctuation mark. It should not be used if it is directly followed by a verb or preposition.
Yes it makes sense but the wording is a little strange maybe rearrange it a little.
it's either a letter, speech, or a diary entry
