Crossing Royal Purple & Coral Blue?

I just picked up four keets last night, and couldn't decide between the Royal Purple and Coral Blue so I got two of each. I'm hoping to get a pair out of the four, so I was just wondering what I might get if one of each paired up. Thanks!

Theoretically since both are partially pearled, all offspring should be partially pearled. Of course if both possess a hidden (fully recessive) no pearling gene, it would be possible to have some non pearled offspring.

The Coral Blues have the recessive blue gene and the Royal Purples have the dominant gray gene. Barring any other hidden recessive genes, all of the offspring in the F1 generation should exhibit the gray coloring because of having the dominant gray gene and should look like Royal Purples.

I suspect that there is a lot more at work here than those simple color genetics. Gray is the dominant color gene and should be the expressed color in any guinea with that gene. I apparently got a Royal Purple in my first hatch this year. To the best of my knowledge, the parents are a Chocolate male and a Coral Blue hen. Neither of those birds show any signs of having the dominant gray color gene.

The Coral Blue hen has the recessive blue gene and it is expressed by being a blue guinea. From the information that I have been able to find, The Chocolate has the buff gene which is also recessive plus a double dose of the DSV (dark shade variant). Theoretically it should not be possible for them to produce a Royal Purple.
 
Interesting, and seems almost impossible to figure out and predict. The one thing that I'm seeing is that they will always produce one of the known colors, is that correct? It doesn't seem like you get random mutts with guineas, or mixed colored birds. Thanks for the help!

Because of so many hidden recessive genes there are a large variety of color variations possible. Just like any other breed or variety of plant or animal, there is always the possibility of a color mutation which while rare can happen. Because of the Dark Shade Variant it is also possible to get varying shades of the same basic color.
