How Does Magenta: The colour that doesn't exist – BBC REEL Work?

Magenta is a color we see on screens and in pictures, but it doesn’t show up when we mix paint like we do with other colors.

Magenta looks like a hot pink or purply red, something you might find on a toy or a balloon. But if you try to make it by mixing red and blue, it just doesn't work the same way as when you mix red and yellow to get orange.

Think of it like this: You have two kinds of crayons, one for mixing paint, and another for mixing light. When you use paint, you start with white and add colors to make new ones. But with light, like on a TV or phone screen, you start with black and add red, green, and blue lights together.

So when we see magenta on a screen, it’s actually made by combining red and blue light, but if you try that with paint, you’ll end up with a purpley brown instead of the bright magenta you expect. That's why magenta is like a color that doesn’t exist in real life when we use paint, even though we see it all the time on screens!

This difference between how light and paint work helps scientists understand more about colors, and it shows us that sometimes what we see isn't always what's "real," but it still feels very true!
