I have decided not to bore you with the standard "gray to gray
gets gray, BV to gray gets 50% of each" etc....
if you need help figuring this,
email me.
Here I will try to explain how double doses of the "ID" genes mix and how these combine with recessive genes to make other colors. 
Black Velvet (half Velvet genes, 1/2 gray) bred to
Beige hetro (1/2 beige, 1/2 gray)
25% each gray, BV, Beige and brown velvet
Black Velvet (half Velvet genes, 1/2 gray) bred to
White (1/2 white genes, 1/2 gray)
25% each gray, BV, white & Black/white cross
Black Velvet to Beige (homo)
50% beige (hetro), 25% each BV and Brown Velvet
Beige (hetro) to White
25% each white, gray, beige & pinkwhite
Beige (homo) to White
50% each hetro beige & pinkwhite
Homo Beige to Pink White
about 50% hetro beige
25% each homo beige and pink white
Hetro Beige to Pink White
50% hetro beige, 
12.5% each gray, homo beige, white & PW
Brown Velvet to White
25% each beige & BV, 12.5% each gray, PW, white and black/white cross.
Brown Velvet to Beige hetro
25% BV, 50% hetro beige
with the rest split to homo beige, Brown Velvet and gray
Brown Velvet to Beige homo
Same as above except there can be no gray expressed,, so the BV goes to brown velvet and the gray goes to hetro beige.
Brown Velvet to Pink White
PW, Brown Velvet, BV, Beige (hetro),
White, Brown/white cross, Black/white cross, Homo beige, Gray

Beige (hetro) to Ebony
This mating produces 25% tan, beige gray and ebony (these last 2 could be gray wrap also)
Black Velvet to Ebony
TOV Ebony, BV, Gray,
GrayWrap, Ebony
White to Ebony
50% gray, 50% white, but could also include ebony/white cross, graywrap and graywrap/white cross
Pink White to Ebony
Gray, Graywrap, Ebony, Tan, PW, White, Ebony Mosaic, Beige, TanWhite
Brown Velvet to Ebony
TOV Ebony, Ebony, Tan,
TOV Tan, Brown Velvet, GrayWrap,
Gray, Beige, BV
Dominate Gene (recessive carrier) to recessive
Note:  violet or saphhire can be switched on the below combos*
White (vc) to Violet*
Violet, White Violet*, White, Gray -
All VC*
BV (vc) to Violet*
BV, TOV Violet, Violet, Gray - all VC*
Brown Velvet(vc) to Violet*
Black Velvet, Brown Velvet, Violet, Beige, TOV Violet,  Gray - All Vio Carriers
Beige (vc) to Violet*
50% Violet, 25% each Beige and Gray
All vio carriers >> if Homo Beige then no gray would be produced.
PW (vc) to Violet*
White, Violet, PW, Gray, Vio/white and beige - All vio carriers
Recessive (carrier) to recessive*
Ebony (vc) to Vio or Saph*
50% violet* with the chance of the darkening ebony gene making the color wrap.   50% would be vc* in gray, gray wrap or ebony.
Ebony to Violet or Sapphire*
All will be vc*,
but with ebony they could be gray, gray wrap, or ebony
Sapphire to Violet
All gray,
all carry Violet (vc) and sapphire (sc)

Tan (vc) to Violet*
Tan, Ebony, Gray, Beige, Violet, Ebony/Violet - all would be vio carriers
Beige (homo) to Ebony
This mating produces 50% beige,
25% each tan & ebony
