Two of the three lights are nearer the yellow table and red wall than the
blue; the reflected light is therefore warm; and even the top one, because
of the relative perceived 'brightness' of red compared to blue, appears to
have a warm tint --- but this is all because of the reflected light. The
shadows, you'll notice, don't look particularly cool in comparison;
comparing light to shadow id  a good way of getting a more absolute idea of
the color of a light.
