The first picture would be just red like and “ Irish” red, the second picture would be considered a mahogany red. In the poodle books I have they describe red as being shades of red , mahogany, red brown given that the dog has a black nose ( preferred) . Brown dogs will have liver colored noses or brown colored noses just like the brown poodle my sister groomed.
Here is the info I was looking for, for you
“DO NOTS
Here are some serious DO NOT's that you should think about when breeding poodles.
DO NOT breed BROWN, CAFE AU LAIT, or SILVER BIEGE (Brown shades) to the following colors: RED, APRICOT, CREAM, or WHITE. Mixing of these colors will cause incorrect pigment on the points since the brown shades have liver colored points and Red, Apricot, Cream, and White should all have jet black points.
DO NOT breed REDS or APRICOTS to the following colors:
SILVER or BLUE. Breeding red or apricot to silver causes the color to fade even more than they already do as the silver and blue colors carries the fading gene. True I have bred blue to red before due to the fact that was what I had to work with at the time. But if you are truly working to deepen and darken reds and apricots and produce beautiful dogs that hold their color, you do not want to introduce any more of the fading gene into these already fading colors than you have to.
When breeding BROWNS, to keep them dark and reduce fading and taking the above rules into account, DO NOT breed to the following colors: BLUE, SILVER, CAFE AU LAIT, SILVER BEIGE. These colors once again will introduce the fading gene into your browns that you are trying to keep dark.
DOS
Here are some very important DOS that you should think about when breeding poodles.
Other than the absolute DO NOT's listed above, how you combine colors totally depends upon what your end goal color is in your breeding program.
When breeding REDS, to keep them dark, to reduce fading, and keeping the points nice and jet black, DO breed to the following colors: RED and BLACK. When using a black every few generations in a red breeding program you will hopefully help to keep dark points on the puppies and also to darken their color. HOWEVER, be very careful what colors are in the background of said black that you do not inadvertently introduce more of the fading gene. I would pick a black that has an all black only background or even better a black that has an all red and black only background (black/red hybrid). Many people consider a color bred red to have apricot in the background. This is because apricot is a dilute of red so still in the same color family. HOWEVER, do not forget that this apricot causes more fading gene to be present in your reds, so the fewer apricots used the better to keep the color.
When breeding BROWNS, to keep them dark and to reduce fading, DO breed to the following colors: BROWNS and BLACK. Breeding true blacks to a brown is a great way to help reduce the fading that we see in most browns. HOWEVER, once again be very careful what colors are in the background of said black that you do not inadvertently introduce more of the fading gene.
As for photographs you would need a hand flash or lots of light on dark dogs ( black) , IMO I do not think a brown dog will be as hard to photograph. I have taking pics of brown dogs and they come out pretty good. It depends what kind of setting you will be using example out door lighting or indoor ?
