You will get partially bearded birds. Not separate breeds, but varieties within a breed. Not a great idea to cross them unless you want a bunch of pet quality birds with very sparse beards and big wattles (usually).
White is a color that acts as an off-switch. Breed white to white generally. If you cross a white to a colored bird results will usually be unpredictable.
Buff and Partridge are colors that you generally want to keep by themselves.
black x black = black
black x blue = 1/2 blue, 1/2 black
black x splash = blue
blue x splash = 1/2 blue, 1/2 splash
blue x blue = 1/4 black, 1/4 splash, 1/2 blue
splash x splash = splash
* This is just a very basic rundown! Even with just your basic black, there are many genes that interact to come up with the correct color. Green vs. purple sheen, miscolor in the hackles, etc. On your blues there is the andalusian blue and its dilute form splash. There is also self blue (lavendar). Birds can have both forms of the blue present to really complicate things. Other colors can also carry self-blue too. Partridge is a fun color to work with but you need separate male and female lines to really perfect that color. Buff is a balancing act. When you start mixing colors, you get some very interesting results sometimes and usually that equates to pet quality culls.
