Caption: A blue toy car under white light (bottom left) and red light (top right). Human eyes respond to the colour of light reflected from a surface. White light contains a full mix of red, green and blue. Blue paint only reflects blue light, absorbing the other colours. Therefore, a blue car appears blue under white light. Red light lacks the green and blue of white light. Therefore, as the blue paint absorbs red light and there are no other colours for it to reflect, the car appears black under red light.
