Strictly speaking, there are only three different types of Labrador colour. Black Labs, brown Labs (usually referred to as chocolate or liver) and yellow Labs.
These are the three colours recognised and accepted by the Kennel Club
In practice, there is a wide range of shades of yellow Labrador colour, from palest cream to richest fox red.
But what makes a Labrador brown, or black, or yellow. And what about Silver Labradors? Where does this new and controversial coat colour come into it?
Labrador color questions
I’ll be answering your questions on what color puppies we can expect when we mate together two Labradors in any of the different color combinations.
And I’ll also explain the genetic code that causes each of the colors in the first place.
I’ll try and keep it as simple as I can!
Understanding how a Labrador’s coat colour is inherited starts with understanding how the three basic colours are passed on from one generation to the next. So we’ll tackle that first.
Where do Black and Chocolate Labradors come from
The information that determines whether or not your Labrador is basically black or basically chocolate, is passed on through a pair of genes.
Every Labrador dog inherits two ‘bee’ genes, one from each parent.
There are two types of ‘bee’ gene.
- One we call big B (this is the dominant gene) and it causes a black labrador coat
- And one we call little b (this is the recessive gene) and it causes a brown or chocolate labrador coat
There are three different combinations of bee genes that a Labrador can inherit from his parents (one from each)
Why black is a dominant color
It is normal for dominant genes to switch off, or over-ride, recessive genes. And that is exactly what happens here.
A dog with BB genes will be black, because he has no little b gene, the one that gives us a brown coat.
How chocolate Labradors are made
Even though a dog inherits a little b gene, the dog will only appear brown if no black gene (B) is present at all. Here are those three possible combinations of ‘bee’ gene that a dog could inherit again, with the coat colour that results.
- Two black genes (BB) gives you a black Labrador
- One of each (Bb)also give you a black Labrador
- Two brown genes (bb) gives you a chocolate Labrador
How colors remain hidden
Although Chocolate Labradors have grown steadily in popularity in recent years, the dominance of the black color enabled our chocolate friends to remain hidden and rare with the breed, for many decades.
Generation after generation of black dogs can continue to have only black puppies if dogs with the Bb gene are only ever mated to dogs with BB genes.
Remember, the dog in the middle of our list above will look black, but pass the brown gene on to about half of all its offspring. But things are never that simple are they? Because of course some Labradors are neither black nor brown.
Where do yellow Labradors from?
So having told you everything above, I’m now going to confuse the issue, and tell you that there are times when a BB, or a Bb dog will not be black at all
The genetic information that creates a yellow coat comes from another pair of genes altogether.
And these genes have a different kind of power. They have power over the ‘bee’ genes.
How yellow can over-ride black and chocolate
Little eee genes are able to influence or in certain cases to ‘switch off’ the ‘bee’ genes that cause black and brown coats. Each dog inherits two ‘eee’ genes, one from each parent. There are two types of ‘eee’ gene.
- One we call big E (this is the dominant gene) and it does not interfere with the ‘bee’ gene
- And one we call little e (this is the recessive gene) and it has the potential to mask or ‘switch off’ the ‘bee’ gene that would otherwise give us black or brown coats. The result is a yellow dog
But little ee is recessive, and if the dominant E gene is present, it switches off the masking gene.
It only takes one big E gene to do this.
So the dog will only appear yellow if no big E gene is present at all.
Each dog inherits one of these ‘eee’ genes from each parent. There are three possible combinations of eee gene that a dog could inherit. It could have
- Two dominant genes (EE)
- Two masking genes (ee)
- One of each (Ee)
Only the middle of these three dogs will be yellow. In the first and third dog, the E gene will switch off the e gene, and the dog’s colour will be determined by its ‘bee’ genes.
Don’t forget these are different and additional genes to those responsible for black and brown. Each Labrador born has a combination of ‘eee’ and ‘bee’ genes. There are nine different possible combinations.
Nine different possible Labrador genotypes!
The chart below lists them (genotype is the genetic makeup, phenotype is the appearance of the dog)
Predicting the colour of Labrador puppies
Trying to work out what colours Labrador puppies will be is difficult without knowing the parent’s genotype.
Because as you can see, the second dog down the list may look black but he could throw brown puppies, and the fourth dog down the list may look black, but he could throw yellow puppies.
Mating two yellow labradors
Two yellow Labradors mated together will never throw brown or black puppies. All their offspring will be yellow.
Mating two chocolate Labradors
Two brown dogs mated together will never throw black puppies because brown dogs do not have the black gene.
But two chocolate dogs can produce yellow puppies, if each of the parents carries the little e gene – see the bottom right hand box below.
Can two black labradors have yellow or chocolate puppies?
Depending on their genotype, two black Labradors can indeed have yellow or chocolate puppies.
Remember from our grid above that there are four different possible genotypes for a black labrador. The genotype refers to the genetic code that the dog carries.
Four ways to be black
In the diagram below, I’ve put the four possible genotypes along the top to represent one parent – the mother for example. And the four different possible black genotypes down the side to represent the father. Inside the grid are the puppies that could be born from each combination.
If and only if, both of them carry one little e gene, then some of the puppies may be yellow. Remember that your puppy needs two little ee s (one from each parent) in order to be yellow.
If only one of the two black dogs carries the little e gene, all the puppies will be black, but half will carry the yellow gene, this is how the colour can skip a generation
The same with the little b gene, if both of the black labs carry one little b gene, around a quarter of the pups could be chocolate, depending on whether or not the double ee gene over-rides the bee combinations!
Is it possible to get all three colors from two black dogs
Yes it is, check out the bottom right hand square in the diagram above. Notice that it can only happen if the two black dogs have this genotype: EeBb
Mating a yellow Labrador with a chocolate Labrador
Now let’s look at what color the pups will be if you mate a chocolate lab with a yellow lab
This is good example of how complicated, and unexpected, labrador colors can be. There are six different possibilities for litter color combinations depending on the genoptye of the parents. You can even get a litter of all black puppies from a chocolate mother and a yellow father (or vice versa)
Here are the color possibilities
- Yellow and black puppies
- All puppies are black
- Yellow, black, and chocolate puppies
- Black and chocolate puppies
- Yellow and chocolate puppies
- All puppies are chocolate
Let’s have a closer look and find out why – in the diagram I have put the yellow Labrador possible genotypes along the top, and the chocolate genotypes down the side.
A yellow dog can be one of three different genotypes: eeBB, eebb, eebb – because anytime two little ee s come together they switch off the three different possible combinations of bee genes.
So, if you look at all the possible color combinations you’ll find that there are possibilities for all three colors in a litter of puppies from eeBb mated with Eebb
Black Labradors crossed with chocolate labradors
We’ve seen that there are four different ways to be black, but that chocolate dogs only come in two different genotypes.
That gives us 8 potential outcomes. The chart below has the different black labrador genotypes along the top, and the chocolate genotypes down the side.
Black labs crossed with yellow labradors
Because there are four ways to be black and three ways to be yellow, there are quite a variety of outcomes for a mating between a black labrador and a yellow labrador.
What about silver labradors?
Last but not least, you may be wanting to know how silver Labradors get their coat color?
Big D and little d.
These D genes have the potential to over-ride all the other colors, albeit in a subtle way.
When two little dd genes are paired together they dilute the coat color of the Labrador that carries them.
In a black dog this gives a softer, charcoal coat colour, in a yellow dog a paler ‘champagne’ yellow, but in a brown dog, the result is the striking silver coat that is currently causing such controversy among Labrador enthusiasts.

It isn’t unusual for people to be quite surprised by the color of the puppies in a litter that they have bred.
Potentially for many generations in a row if they are carried on a recessive gene.
And if you think think Labrador genetic is complicated, try working out the genotype of a cocker spaniel
It comes in a veritable myriad of different colour combinations.
It is enough to make your head spin!
