Well, I put no consideration into their puppies, but it turns out they've had quite a few beautiful outcomes!
I made Tigress with her colours because I have an attachment to the yellow and royal purple colour scheme, though I tweaked hers a bit from the original inspiration. If you think about her name and American college football at the same time, maybe you'd get it XD I think the colours are gorgeous together! I love white underbellies, so I went with that, and for her eye colour I picked white since I'm not the biggest fan of how the eye colours can look on this game. But I also got inspired from my pre-release progens on the eye colour, since at least one had near-white eyes. Also, I've always been a fan of the base colour matching the accent colour in any game like this (and in fashion! Match my shirt colour with my shoe colour !)
I'm only just now realising my progen's IDs are several digits apart, but here's Niagara. Now, Niagara was simply based on, well, kind of like a waterfall theme. I like that blue and yellow together as it reminds me of the sun and rushing water. White underbelly again, because if I were to breed my progens I know I wouldn't want a muddy undercoat colour, and the Slate accent just because the contrast looks nice. Sepia eyes, not sure it was the best choice but I did want a sort of yellow-brown eye that felt soft as I think it makes him look kind.
I picked two different breeds because I knew I'd want more than one breed possibility for their pups. Just to give some variety, and so I wouldn't have all the same breed to begin with.
Yeah, my explanation is long but I did put a bit of thought into my progens, beyond just things that I like. Though I did rush and if I'm being honest, not sure if I would pick the same on the second go around if I was able to have one.
