Demi-permanent color is a type of oxidative color treatment that does not lighten the hair. It gradually fades over time and leaves the hair with a deeper or changed tone. Permanent color, on the other hand, uses a higher level of developer and can lighten the hair as well as deepen or change the tone. Semi-permanent color does not use a developer and only coats the hair, providing a temporary change in tone. Brown is not a type of color treatment and therefore is not the correct answer.
