I think it's a beautiful name streaked with "twilight" colors: pastel purples, blues and greens. The pronunciation (at least, the one from Google) is just gorgeous and contributes greatly to its shape and depth. It hardly seems human, rather, I think of it as the name of a whimsical, mischievous sprite. Does that make me stupid? Well, that's up for you to decide.
Nishant, end of the night. In addition it contains the Sanskrit word shanti which means peace. This implies that Nishant means what we call first light in American English, or the time of day between night and sunrise.
