A sprayer including a sprayer container adapted to be filled with a fluid. The sprayer container has at least a portion thereof including thermochromic color-changing properties. The sprayer container includes an interior surface and an exterior surface. A spraying gun is connected to the sprayer container, with the spraying gun including a trigger for selectively spraying pressurized fluid in the sprayer container onto a predetermined object. The sprayer container indicates the amount of fluid in the sprayer container by a color change line located at a transition line between the fluid and gas within the sprayer container when fluid is located within the sprayer container, thereby causing a top area of the sprayer container having the interior surface adjacent the gas to be a first color and a bottom area of the sprayer container having the interior surface adjacent the fluid to be a second color.
