A cute onesie for my son, but the yellow is lighter in real life than it appears on my computer screen or on the TV show. In other words, it's still cool, but not as cool as it would have been had they gotten the color right.  That being said, I also bought my son a blue science officer's (Spock) onesie, and that one looks great.  The color was on point, and the Starfleet logo pops better against the blue.  Yes, I know, I'm a total nerd.  Live long and prosper.
