Shortcut for right-click colorful headers

I often use the right-click H1, h2, h3 formatting that colors the entire paragraph. I find that they are more useful for quickly scanning a page to see different categories of notes like literature info, personal notes, and so on.

There is no way that I have found to use this formatting without right-clicking the tiny paragraph bullet. Can a keyboard command be added? Currently, the # ## ### (or /h1 /h2 /h3) formatting option (a completely different H1 h2 h3 I assume??) only makes text changes, not color. If this feature already exists, I have not found it! Thank. you.
