I recently came across a product called Vanish Miracle that claims to improve the colour of the clothes. There’s even a hash tag on Instagram and the results that people have are pretty amazing. I remember that years ago there were similar products but only for white or black clothes.
How do they actually work? I understand that for whites it might be bleach, but making a yellow shirt be more yellow or a red scarf be more red seems magical. What’s the secret?

I can’t recall what class it was in but my prof got into a bit of a side discussion which involved telling us about old detergents that were designed to make whites look whiter by adding a tint of blue because it actually looks more clean and vibrantly white than an actually pure-white shirt. He explained the reasoning but I can’t remember it fully other than having something to do with natural light and our perception of colour.
