A chemical change. Color change is a good indicator of a chemical change.
Chlorine dioxide can change water from blue to yellow due to its yellow coloration. This compound is an oxidizing agent commonly used for water disinfection, but exposure to sunlight can break it down, which can lead to the color change in water.
they dont get sunlight
A chemical change has taken place. The exposure to sunlight causes the paper to undergo a chemical reaction, breaking down the molecules in the paper and causing the color change to occur.
Sunlight has seven colors because the atmosphere acts as a filter, it changes the color, for instance the setting sun, looks yellow or orange.
Yellow.
When red and yellow paint are mixed together, the color of the painting changes to orange.
Ordinary yellow sunlight becomes a rainbow when different frequencies of light are bent in slightly different directions.
It means that it is time for an oil change. I just found that out. Usually when you get an oil change from a professional place they reset the light for you. If you do the oil change yourself, then you must reset that light yourself. Its easy, under the maintenance required light is a hole, I though it looked like an alarm sensor but I was wrong. That's were you stick your key in the hole and the light changes from Yellow to Red then Green. Green represents, you have complied and the car can go 3000 miles, until the light changes Yellow. Yellow represents (Warning) it is time for an oil change. If you don't change the oil and continue to drive another 1500 miles the light changes from Yellow to Red.Meaning (Danger) now it is def time to change the oil.

yellow (Y)
A yellow cloth illuminated with direct sunlight would appear yellow, with its color looking bright and vibrant due to the full spectrum of light present in natural sunlight.
there not. they shine in the sunlight but thats it.
Phenol red changes yellow in acidic conditions due to a shift in its chemical structure, which occurs when the hydrogen ions in the solution cause the indicator to undergo a color change. This change is reversible when the solution becomes basic again.
