phisical, unless using bleach. bleach actually changes pigment, while normal dye just covers-up the existing color.
No, bleach changing the color of a shirt is a chemical change. The active ingredient in bleach, sodium hypochlorite, reacts with the dyes in the fabric, breaking them down and removing their color. This results in a permanent change in the chemical composition of the fabric.
Mixing bleach and red food coloring would be a chemical change because it results in a chemical reaction that alters the chemical composition of the substances involved, causing a color change.
A chemical dye that changes color based on the pH of a solution is called an pH indicator.
It changes the sugar's color
Phenolphthalein is a chemical that turns yellow when sprayed with bleach. It changes color in response to changes in pH levels, and in the presence of bleach its color shifts from colorless to yellow.
It is bleached by the ultraviolet rays in the sunlight.
When chlorine bleach changes the color of brightly colored clothing, it is typically a chemical change. The active ingredient in chlorine bleach, sodium hypochlorite, can react with the dyes in the fabric, causing a chemical reaction that alters the color of the clothing irreversibly. This is different from a physical change, which would involve a change in appearance without altering the chemical composition of the material.

Bleach can cause red clothes to turn white or pale pink due to the chemical reaction with the dyes in the fabric. The bleach breaks down the color molecules, leading to a lighter or faded appearance. It's important to be cautious when using bleach with colored clothes to avoid unwanted color changes.

Color and density are physical properties, not changes.
It is a chemical change. The bleach reacts with the pigments in the hair, causing a chemical reaction that breaks down the natural color and can result in a yellowish tint.
An oxidizing bleach works by breaking the chemical bonds of a chromophore (part of a molecule that has color). This changes the molecule so that it either has no color or else reflects color outside the visible spectrum. A reducing bleach works by changing the double bonds of a chromophore into single bonds. This alters the optical properties of the molecule, making it colorless.
