Explanation:

- The sentence discusses the dual nature of colors, highlighting their calming effects and their ability to energize or activate.

- Option 1: "involve" doesn't fit well with energizing and activating; it's more about engagement or participation.

- Option 2: "envigorate" (correct spelling should be "invigorate") aligns perfectly with energizing and activating. It means to give energy or life to something.

- Option 3: "enrage" refers to making someone angry, not energize or activate.

- Option 4: "interest" is about capturing attention, not specifically about energizing or activating.

Your selection with "envigorate" suggests a fitting continuation of the energizing theme.
