Water and bleach are very different, especially when vivid colors are involved.
Water and bleach: historically, this pair go together pretty well, namely in the world of cleanliness. Bleach is a remarkably caustic base that, when diluted with water, can clean stains from whites and linoleum. However, apart from their similarly clear appearance, water and bleach are very dissimilar. Bleach is very alkaline, but water is a neutral pH. Chemically, that is saying a lot. But what does that have to do with vivid colors?
