Good chili powder, that is mild [duplicate]

I am looking for a mild red Chili-pepper with all the flavor of a spicy red-chili, but without the heat of one.

My Aunt likes spicy food as well, but it doesn't agree with her. Often I make mild versions of the spicy dishes I make, as a way of showing gratitude for helping me out. I love my Aunt so much, and I want to give her access to spicy dishes without so much spiciness, but despite my efforts, the mild dishes just don't taste as good as the spicy versions I make.

From what I have seen on labels, and read on the internet, red chili powders & red chili flakes are often produced using various different breeds of cayenne peppers, or at least where I am at in the USA.

Does anyone know if there is mild chili-pepper that is capable of recreating the flavors come from cooking with regular spicy red-chilies (or cayenne peppers)?
