An object's colors act as discriminate reflectors meaning they will only reflect their own color. The reason why we can see all the colors present in the objects around us is because white light contains all the colors of the visible spectrum of colors, so it highlights them all. This concept of how light works becomes important when we want to highlight something in a certain way. For instance let's say we have a red rose with a green leaf. If the rose was lighted with only a red light the green leaf would appear to have no color or it would appear to be black. This concept could also be flipped the other way in lighting the rose with a green light the red rose would appear to have no color or look black. Remember if the color isn't in the light source you won't see it in the object being lighted. When we look at the color light spectrum there are colors that are weak at certain points and stronger at others. If you have a light source that is stronger in any one color or colors it will tend to emphasize those colors and mask the other colors present.
Although the original strip light is not known for its aesthetically pleasing qualities, the newer versions of this lighting solution are much classier than the original, retaining their modern look but instead being more delicate and discrete, emitting a more pleasant light. Like the other two types of LED cupboard lights mentioned above, strip lights can be placed on the underside of cabinets to illuminate work surfaces,and can be battery powered or plugged into the mains, depending on the preferences of the homeowner.
Light quality and colour can dramatically change the appearance of a room so it is important to get this right. You wouldn't, for example, want bright white lighting in a bedroom, instead a soft warm white ambiance would be more suitable. When choosing a light bulb you first need to decide which colour temperature you require. Colour temperature is a measure of how warm or cool a colour appears. It is measured in Kelvin; the standard measurement for lighting output in addition to lumen output. Colour temperature is derived from the colour of light produced when carbon is heated. The Kelvin Scale ranges from extra warm white at 2,700k giving a warm yellow glow, to white at 3,500k, cool white at 4,000k and daylight colour at 6,500k which produces a white blue colour. LED, CFL and halogen energy savers are all available in a range of colour. Complaints have been made in the past about LED giving off a cool blue light but with the improvement in technology, as long as you buy a good quality LED this should not be a problem. It is then important to look at the colour rendering index (CRI) which shows to what extent the light will make an object appear its true colour. An incandescent bulb is rated at 100% because its light contains a full spectrum of colour. CFLs do not contain the full colour spectrum but a good quality triphosphor fluorescent rated between 80-90% will be sufficient for everyday use. Higher rated CFLs can be obtained but are usually only used by designers or artists and are less efficient. It is advisable not to buy a light bulb which scores below 80% on the CRI scale. Energy saving light bulbs have received a bad press at times because of the light they produce, but this has tended to be because many poor grade CFLs either brought from supermarkets or given out for free by energy companies have come onto the market.
