What two factors determine the color of an object?
1. the material the object is made of and its shape
2. the color of light that strikes the object and its shape
3. the material the object is made of and the amount of light in the area
4. the material the object is made of and the color of light that strikes it

Answer;

4. the material the object is made of and the color of light that strikes it

Explanation;The color of an object is the wavelength of light that the object reflects, which is determined by the arrangement of electrons in the atoms of the material making the object.We could therefore say that the color of object depends on or is determined by the material making up the object as this determines the the wavelengths of light the object reflects. Lastly, the color of light source also determines the color of the object.
