To Cap or Not To Cap (after a colon)?

Don't expect a "rule"! There are many, but they don't all agree. If you feel what follows a colon is simply a list or series of things, don't bother with caps. If you prefer to capitalize the first word of a sentence that follows a colon, do it. That's what grammar anarchy is all about. YOU choose. Don't forget to record your choice in Your Style Manual.
