The effects of different types of artificial lighting
In residential and commercial spaces, artificial lighting is frequently used to either supplement daylight or replace it entirely. The type of artificial lighting used plays a large role in how a color looks.
• Incandescent bulbs: These generate yellow light that intensifies warm colors but tends to dull cooler colors.
• Halogen bulbs: These newer incandescent bulbs produce brighter, white light that is more like sunlight.
• Fluorescent bulbs: These generate cool, blue light that amplifies blues and greens, but mutes warmer colors.
• "Soft white" fluorescent bulbs: These mimic the warmth of incandescent bulbs, but all colors can appear faded in their light.
• Full-spectrum fluorescents: Although expensive, these bulbs produce light that most closely resembles natural sunlight.
Incandescent and halogen lighting tends to warm up reds and yellows because the wavelengths of these artificial lights are warm. So, if a client has incandescent light fixtures in a room where they want blue walls, you'll have to make color adjustments
when it comes to picking the paint, such as selecting a blue hue that has been toned with red.
The type of light fixture can also affect the coloration in a room, because the fixture typically determines how the light from any type of bulb is dispersed.
• Sconces: These fixtures give off indirect lighting by aiming the light toward ceilings or walls.
• Shades: Lampshades will change the coloration and strength of the bulb inside them. If the lampshade is of a warm hue, it will cast this glow onto the other colors in the room. Strongly colored shades will mute any surrounding colors, while white or ivory shades will give off the brightest light.
• Parabolic lights or downlights: They direct light straight down from the ceiling. This provides a lot of light on work surfaces and floors, but can cause ceilings and the top edges of walls to appear dark in comparison.
To create a crisp, airy atmosphere that will show off bright colors to best effect, consider using bright-white light bulbs, or some of the new fluorescents or halogens. For a warmer, cozier look that works well with darker colors and rich textures, go with light-pink bulbs, or even amber-colored accent lights in sconces.
