PERSPECTIVE.
Every object devoid of colour in itself is more or less tinged by
the colour of the object placed opposite. This may be seen by
experience, inasmuch as any object which mirrors another assumes the
colour of the object mirrored in it. And if the surface thus
partially coloured is white the portion which has a red reflection
will appear red, or any other colour, whether bright or dark.
PERSPECTIVE.
Every opaque and colourless body assumes the hue of the colour
reflected on it; as happens with a white wall.
