Gadget color

Every member of the Wild Kratts Crew presumably has a gadget color that is the color used for various devices.

Creature Power Suit
The Crew only possesses two powers suits: Martin's and Chris'. The two suits are each blue and green (the colors of Martin and Chris, respectively). But when it is worn by another Crew member, the suit changes to their gadget color. However, when deactivated, the suit is either blue of green no matter which member it is on. Examples:
 * When Martin activates his power suit, it is blue. It is blue deactivated as well.
 * When Chris activates his power suit, it is green. It is green deactivated as well.
 * When Koki activates Chris' power suit, it is yellow. But is is green when it is deactivated.
 * When Aviva activates Martin's power suit, it is pink. But is is blue when it is deactivated.

Creature Pod
The Crew seems to be in possession of three or four creature pods. Martin and Chris are known to each own one. Aviva has been seen with a pink Creature Pod (staying consistent with her gadget color from the power suit), but it is unknown if this is her own pod, or if a Creature Pod changes color when it comes in contact with another Crew member, like the Power Suits do. Koki has also been seen with a Creature Pod, this one dark red. Examples:
 * Martin's creature pod is blue.
 * Chris' creature pod is green.
 * Aviva's creature pod is pink.
 * Koki's creature pod is dark red.
