Yes.
The signs of a chemical change are:
- Change in smell
- Sounds
- Change in color
- production of gas
- change in temperature

answ2. Colour is a physical property.
When illuminated by a white light, the colour seen of an object is that of the wavelengths of light NOT absorbed by the material.
For example, sulfur appears yellow, because all other colours are absorbed by it.
You may demonstrate this by illuminating your subject by a series of light samples, each passed through narrow-pass optical filters. Only that passed through the yellow filter will let the sulfur colour show.
A Gedanken experiment suggests that a rainbow of light from a prism should demonstrate this as well.
This might make a suitable experiment for a school science show????

∙ 13y agoColor itself is not a chemical, but some chemicals are colored, and chemicals play a role in the perception of color.
From the point of view of a human color indicates the wavelength at which light is reflected from a surface. Different materials absorb and reflect light in different ways. This leads to the wavelength of the light being reflected being changed. Our method of perceiving light (vision) can differentiate these wavelengths (by their effects on chemicals in the eye) and we see this as color. Not all animals see color exactly as we do (their eyes may be based on different chemicals, for example), but the basic mechanism is the same.

Is color changing in leaves a chemical change or a physical change?
a chemical change
Is changing of color a sign of chemical change?
The change of color may be a sign of a chemical reaction.
Is changing color of a carnation a chemical or physical change?
It is a chemical change.
Changing color of acids is chemical change?
Most circumstances of colour change are chemical.
When you dye your hair is that physical change or chemical change?
Yes it is a chemical change because color change is an observed change that a chemical change has occurred. So you are very much right. :)
Is color changing in leaves a chemical change or a physical change?
a chemical change
Does the color of the fruit affect the chemical change?
only if you need to research the color of the chemical change
Is changing of color a sign of chemical change?
The change of color may be a sign of a chemical reaction.
If the color changes it is a chemical or physical?
- Color is a physical property and the change of color also.- Color change may be a sign of a chemical reaction.
Is a color changing in leaves a chemical change or physical change?
Chemical Change.
Is the change in leaves a chemical or physical change?
The change is leaf color is a chemical change.
When could color change be a result of a physical change?
A color change is only a chemical change if the change is permanent, if the color change is not permanent, then it is likely a physical change. Let's look at Iodine for example (that's pronounced Eye-oh-deen), it is a solid metal that is grayish in color in its solid state, however in its gas state it's a purple or violet color. Once it reverts to its solid state, it turns gray again. This is a PHYSICAL property of Iodine. If the color changed permanently to something else, it would be a chemical change.
Color is a phyiscal change?
Color can be anywhere from a physcal change to a chemical change.
Is a color changing in leaves a physical or chemical change?
a chemical change
Is changing color of a carnation a chemical or physical change?
It is a chemical change.
Is the Change of color a physical change?
it is a chemical change
Is a change in mass an indicator of chemical reaction?
No, it is NOT an indicator of a chemical reaction. Change in color IS an indicator of chemical change, though.
