The race Kave is from

these color combinations are the most common. White hair is a bit rare, but it still happens. Most of the time people with white hair have power over ice instead liquid water, like blue haired people. Everyone's hair is slicked back to make swimming easier. Their curves also help, and so do their dorsal fins on their arms and tail. the top eye colors are orange and green. Not blue, which most people think.

Kave has an affinity over fire, not water. His race originates from a fire race, so its not really a surprise to most people that he is unlike so many dragons in his homeworld.
