Tabby is a pattern, not a color.
You have two basic colors, black and red. Male cats usually have only one of the base colors, females can have black and red at the same time which would make them torties.
There are two colors derived from black; chocolate and cinnamon. Those colors can also combine with red to make chocolatetortie or cinnamontortie for female cats.
Then there are dilute colors, caused by the dilution gene. Under the influence of the dilution gene;
black becomes blue
chocolate becomes lilac
cinnamon becomes fawn
red becomes cream
In tortie cats both colors become dilute, so you can have bluetorties, lilactorties and fawntorties, those all have cream spots in stead of red spots.
White isn't really a color, but absence of pigment. There are two forms of white, one form that causes spots of white (can be very small or so large they almost cover the entire cat) and one form that makes the cat completely white.
Male and female cats with one color + white are bicolored.
Torties have two base colors and when they also have white spots that makes them tricolored.
Now for tabby; as I said before tabby is a pattern, that pattern can occur on all colors I listed above, except on white, because that isn't a color. You can have blacktabbies, bluetabbies, chocolatetabbies, creamtabbies, you name it.
A tabby cat with white spots is a tabby bicolor. A tabby cat without white spots is not a bicolor, because it has only one ground color. I know the pattern on the cat is made in a different color, but it's only the ground color that counts for the name bicolor/tricolor. Just one of those things
When a tortie cat also has the gene for the tabby pattern the resulting look is called tortietabby. A tortietabby with white is also a tricolor.
When people say tricolor males are rare, they mean males that are tortie, not tabby and white males. (unless they are tortietabby
).
From their profile pictures Jordan and Maggie look like black tabby and white cats to me. (there are some people who would say brown tabby and white, but because they have the black gene I prefer black tabby and white)
There are four different tabby patterns, ticked (each hair has colored bands but overall you see little to no pattern like on Aby cats), mackerel (stripes on the body), spotted (spots on the body) and classic/blotched (swirled pattern on the body). You could add the pattern to the description of your cats after the word tabby.
I hope that was helpful because I typed this up after I'd decided to go to bed, it's near midnight here and I'm a bit sleepy
