A quote from (though almost certainly not Legends-canon) Star Wars Adventures in Colors and Shapes suggests that he cannot:

C-3PO: "Excuse me, Central Computer, but could you tell me if this plate is red?"

Central Computer: "No, that plate is green. Green is the color of grass, and of leaves on the trees, and of Greedo."

However, in Star Wars: Droids (also probably not Legends-canon), C-3PO solves a color puzzle.

In the Knights of the Old Republic RPG series, when you control a droid and view in first person they have monochrome vision, so perhaps that is the norm. However, I'd expect a protocol droid to need detailed vision.

I did not find much about C-3PO commenting on colors in a short search, and I don't remember anything from books. So, does C-3PO have color vision?

    He knew he had a red arm in TFA.

  • In the quote, it sounds like he's asking if the color he's seeing is red.

    @Jeeped: Do we know how he found out his arm was red? Did he simply see it, or did someone tell him?

  • @DeeV he's looking for a red plate to replace a damaged red plate. He (apparently) can't tell if the one he has is red or not. It's a children's book.

1 Answer 1


According to the Star Wars Blueprints: The Ultimate Collection factbook, C-3PO has a Mk.2 Myriad Visual System that gives him vision equivalent to that of a human. This presumably includes colour-vision.

C-3P0 information

A salvaged MK. 2 Myriad Visual System allows C-3PO to see by human and various alien standards.

The Star Wars: The Visual Encyclopedia factbook goes even further in describing his visual systems. In "human mode" he has the equivalent eyesight of a human, but in other modes he can see into the infra-red, lowlight night-vision and analyse gases.

C-3P0's visual hardware and software allow him to see much more than the average human. Each of the settings of his Myriad Visual System—MK. 2 provides a unique optical advantage. Human mode gives C-3P0 a standard visual reference, while Infra-red mode lets him see at night. Other modes allow him to scan for properties such as gas composition, heat, or motion.

  • Shouldn't you provide a full transcript so readers can get more information, even if the image is not displaying?

    @Voldemort'sWrath - A full transcript isn't always necessary, but a partial one (of the relevant bits) is useful.

  • I thought one of the encyclopedia's would have it but I don't have one myself. This is a good answer.

    @gormadoc - I find that it's useful to own practically every in-universe Star Wars factbook ever written
