Between two clauses
When you have two independent clauses, and the second one comments on or explains the previous clause—you can use the colon punctuation mark:
Example:
He came later than usual: his wife accidentally took the car keys when she left for work.

The colon before a list
Do you use a colon before a list? You may need the colon to list items in a sentence:
Example:
The program includes various activities: swimming, yoga, dancing, bicycling, and rock-climbing.
But be careful not to put it after a preposition:
Example:
We have pizzas with pepperoni, shrimp, and cheese.

The colon before quotes
To introduce a quotation, it’s good to mention its author. Also, sometimes a quotation is included in a sentence. In this case, you may need some punctuation:
Example:
The sign was challenging to understand, as there were missing letters, but it read: “Dangerous! Use the side road!”

Colon grammar rules to make an emphasis
Sometimes it’s essential to add some emotion to the text. But the question is–how to punctuate correctly? The uses of a colon in punctuation can emphasize a phrase or a word at the end of the sentence:
Example:
This relationship was interesting, lively, and fun, but she didn’t get the only thing she really needed: the truth.

Do you capitalize after a colon?
We often hear this question and can’t ignore it!
The rule is easy. You should capitalize after a colon if it’s a complete sentence:
Example:
Something can go wrong: We can catch the flu. You can lose your money. We can miss the plane.
You should also capitalize the first letter if it’s a proper noun:
Example:
No, only several students came to the lesson: Julie, Chris, Diana, Michael, Peter, and Lisa.
In other cases, you don’t use capital letters:
Example:
Every detail of the skirt she made was perfect: pockets, the belt, and black laces.
