Our Color Temperature Control System allows you to enhance your art by varying the colour output from our picture light via a small remote.
This cannot be achieved by illuminating with single source bulbs like incandescent or halogen.
The art work below shows the color temperature changing from a candle temperature through to daylight.
The advantage of this system is you have the power to slightly change the color of the light allowing you full control over your paintings look and feel.
For example with the painting of the ship below, the color of the scene can be tweaked to bring out the red flag and figures on the ship. These details can be lost with conventional lighting. This gives you full control over the display of tones and hues in your painting, lighting your painting to best effect!
The best temperature for the above art work is 3000K to Halogen.
The remote also has a dimming feature from zero/off to maximum.
Being able to choose your illumination temperature onto your art gives a staggering effect. See our Tonal Control System which is more complex.
Hogarth's Tonal Control system allows you to enhance your art works color temperature.
To date there has not been a way to illuminate art works perfectly, the main problem is that bulbs (incandescent, tungsten, halogen etc.) emit a certain colour temperature, no matter what type of bulb is used it will not compliment all of the pigments within an art work or give the same temperature as when the artist created the painting - the color the artist intended.
Via our small hand held remote it is possible to:
Our test art work below shows all the problems of illumination.
The Sea is predominantly green. The sky is moody grey, just after a storm still raging to the far left. At the top right there is blue sky breaking through the creamy white clouds. The Flags have red stripes, the sails are lit by the sun breaking through to the right, making them shine with warmth.
This art work could not be illuminated well by just one type of bulb, certain areas of the art work need adjustment to highlight them.
The beautiful blue sky top right is cooler than it should be, the red stripes on the flags and along the deck could be enhanced.
Even if illuminated by halogen or cooler temperature bulbs there would still be pigment areas that would look wrong - not as the painter intended. due to the colour temperature of bulbs.
Further example: a red Ferrari sports car will look red in sunshine. Park the car in a garage with halogen bulbs and the red will look different. View the car in a showroom illuminated by tungsten bulbs and the red will look different again.
There are ways to measure the ability of how a bulb changes the color of an object or the pigments in an art work known as Colour Rendition (C R I - Colour Rendition Index).
To help with understanding some of the references within our system, Noon daylight is measured to be around 5500K (Kelvin) and is classed as being quite a white source of light. A candle will give off a very warm light at around 2000K. An incandescent filament bulb is cooler than a candle at 2600K and halogen bulbs are cooler still at 3500K with fluorescent bulbs at 4500K.
