Obi-Wan Kenobi - 10 Things You Missed
6. Obi-Wan’s Droid Has A Deeper Meaning
In the final episode, Obi-Wan Kenobi slashes Darth Vader's helmet, revealing his disfigured visage underneath. During this confrontation, many viewers noticed the glow from Obi-Wan and Vader's lightsabers lights up Darth's face to symbolise his inner struggle - the blue light represents good, while the red light represents evil.
Even though most viewers should've picked up on this, this type of symbolism was used more subtly in the opening episode. In one of the show's first scenes, we see Obi-Wan arriving at his home. As he approaches, a droid hidden underground pops its antenna out and emits a blue light to affirm there's no danger.
When our hero arrives at his house later, the droid pops up again, but this time, flashes a red light. Obi-Wan immediately becomes wary, knowing the red light signifies there's an intruder in his quarters.
It may seem like a minor moment, but it demonstrates a central rule in the Star Wars universe - blue represents good, red represents evil. Because the same colours are used to represent Obi-Wan and Darth Vader, this added touch is greatly appreciated.
