Sorry if this has been asked before, I couldn’t find it! But do Hellhounds have the same kind of colorblindness dogs do? Or do they see colors normally?
Generally speaking they see colors normally! Every species might have some nuances in the colors they see, but generally everyone has same or similar color range.
This can go into the evolution of species, since there are multiple sentient species on this planet, each with unique needs but ultimately the 'dominant' species in their region during early development, they'd need to develop color sight for survival much as humans irl have done. This isn't to say that some species might have limited or very different color capacity (in case of underground/underwater species), but generally speaking, they're all pretty on par with each other. :)
