That red is a lilac. it is a double recessive gene of the black. One, because it is a chocolate, Two because it has the blue gene that causes the silvery sheen. I will attach the acceptable hound colors to this post so you can see there is no marking for lilac. You have to go with the dominant color on this hound which is blue. Its confusing I know.
You are correct about the tri color's. Most beagles ARE tri-colors. Maybe this will help ya understand the differences on how hounds can be tri's yet be different colors. No laughing at my ugly dogs, lol.
This is Southern Pepper. She is a tri color. She is AKC registered as a Blue Fawn and White. Note the tri color pup next to her on the bench then compare the colors on the blanket.

This little Southern Little Red Corvette. She is a tri color. She is AKC registered as a Brown Tan and White. Her color is also called a Chocolate.

This is Southern Domestic Dispute. He is a tri color. He is AKC registered and a black, tan and white.

This is SOuthern Swamp Booger. He is a tri color. He is AKC registered and a Black White and Tan.

This is Southern Pee Wee (Squirt). He is a Tri Color. He is AKC registered as a Black White Tan w/ ticking.

This is Southern Eight ball. He is a tri color. He is registered as a Black and tan Bluetick.

The AKC doesn't allow all of the colors of these hounds so we have to get as close as we can to the true markings. For example, dog #2 Little Red Corvette is closer to a red, tan and white but the AKC doesn't have that option on the list for colors.
Below is the list of colors for beagles. Note that Bluetick is not an option alone for beagles. Also note that there is no color marking for black tick. I hope this helps you understand where we are coming from.
