A few ways to affect colour through lighting:

 To warm up a room’s Colour: Look for a bulb with a temperature close to
2,700 Kelvin. Halogens are a good choice, but all types of bulbs are available
in warmer ratings.

 To cool down a room’s Colour: Look for a bulb with a temperature close to
4,000 Kelvin. Standard fluorescents will generally cool down a room, but
check the numbers.

 To most accurately replicate natural daylight: Midday sunlight is around
5,000 to 6,000 Kelvin, but keep in mind that this is very cool light — contrary
to what you might expect.

 Adjust bulb Colour with fixtures. If the Colour of light produced by a bulb isn’t
quite to your liking, you can tweak it by picking a fixture shade that changes
the light. But know that an enclosed shade on a fixture that hangs upside
down like this has limited bulb options.

LED bulbs will not last as long if they’re exposed to the heat build-up in an enclosed shade.
While it is true that white reflects light better than any other Colour in the Colour
spectrum, it doesn‘t mean that you have to only use white on your ceilings. In fact,
adding Colour to your ceiling can draw the eye upward and make your room feel and
appear larger.
