Science, The Power of Bleach

We had great fun experimenting with household bleach.  We predicted the water would change to blue when we bleached navy blue cotton fabric, and were surprised to find it went orange, the material also changed to a red/orange colour but the cotton stitching stayed navy blue. We learned that natural fabric such as cotton bleaches more easily than nylon.  Bleach releases oxygen molecules = oxidation, this breaks the chemical binds of chromophores.   Chromophore molecules either reflect no colour or a colour outside the visible spectrum.
No colour is white to people.
