Also here is a quote from each Raptor from the Lego infographics that were released today. It also reveals how each Raptor got its individual colors. If don't want spoilers, don't read these.
Blue:
"In the late Cretaceous Period, the Velociraptor excelled at hunting with its keen senses, large brain, and the retractable sickle claw on each foot – and no creature in Jurassic World demonstrates this better than Blue, the leader and oldest member of the raptor pack. Larger, smarter and more cunning than the rest, she insists on eating first…which is why Own feeds her last so she remembers he’s in charge. DNA from a Black-Throated African Monitor Lizard provides her distinctive pattern of scales, which reflect an iridescent blue color."
Charlie:
"Charlie is the youngest member of the current raptor pack, and its least-experienced hunter. Her instinct-driven reactions make her hard to predict, so Owen never takes his eyes off her during training sessions. As the “rookie” of the group, Charlie looks to Blue for guidance and commands during hunts, and will immediately give up a meal to her pack leader. The InGen scientists have genetically programmed her with the dramatic striping of a large Green Iguana."
Delta:
"The second-eldest member of the raptor pack, Delta shows the signs of InGen’s genetic experimentation and modification in several ways. Along with her unique gecko-like pupils, she has been infused with more avian DNA than her sister raptors have, resulting in her very bird-like movements and behaviors. Being watched by Delta is a lot like being stared at by an eagle about to launch an attack."
Echo:
"When they were both young raptors, Echo once challenged Blue for command of the pack. Unfortunately for her, Blue was the stronger fighter, and Echo was left with the permanent scars of their encounter across her face. Because of her permanent sneer, some of the Jurassic World dinosaur handlers have nicknamed her “Elvis”."
