How Does Marvellous Madder The Colour Change Dye Work?

Marvellous Madder is a special kind of dye that changes colour when it meets something else, like how your favourite shirt changes from blue to purple in the washing machine.

Imagine you have a bag of crayons. If you use just red crayon, you get red. But if you mix red with yellow, you get orange. That’s kind of what Marvellous Madder does, but instead of mixing crayons, it mixes with something called alkali, like baking soda or soap.

When the dye meets the alkali, it changes from one colour to another, just like how your shirt goes from blue to purple when you wash it. This means the same fabric can look different depending on what it's mixed with!

It's like having a colour-changing toy that works with real stuff you find at home, instead of needing batteries or buttons. You just add some soap and watch the magic happen, well, the science happen!
