When light passes through a colored translucent object, how does the light take on that color. (How does the light “pick up” the color of the thing it passes through?)

White light contains all colors in it. The colored translucent object absorbs all the colors except the color it lets through.
For example, red stained glass absorbs all the light except for the red which passes through.
