No worries, please feel free to ask anything here.
Let's see if this helps:
nn - Nn - NN (nn being normal neck)
black - blue - splash
Black is "no blue" just like nn is "no naked neck".
Blue is one dose, same as Nn- big bowtie/bib.
Splash is two doses, same as NN - tiny bowtie or totally clean neck.
It's the same idea of two doses of the gene has 'stronger, more effect' on the bird. NN is more naked than Nn, splash is "more blue(actually diluted" than blue.
The other thing about blue... it primarily affects black pigments and has minimal effects on red/gold pigments.
So.. a solid blue or a "solid splash" are really solid black chickens with one dose of blue and two doses of blue, respectively.
On color patterns like a black tail buff, only the black tail(and any other black details) get turned to blue or "splashed" while the red/buff is usually either totally or only slightly unaffected. That's how the parents of your bird came to get their grey tails.. and since both parents had blue, there was potential for splashes(double dose of blue) just like two Nn parents have the potential to produce NN.
