Recently I invested in a few energy-smart light bulbs but probably not for the purpose that you’re thinking (not that there is anything wrong with that). I have been doing a lot of research on color management of LCD displays and projection.
You would not believe what must be taken into consideration when you are trying to match the color of your computer screen with what you print or an image you’re projecting. Alas, I will not go into all of this.
What I will tell you is a simple way that you can control one of the factors of how color displays on your monitor, by controlling the light in your room and the environment around your computer. I’m sure you have noticed that there is a difference in brightness, and color of light emitted from your respective lamps. Well, the factors you can control are the color and brightness of your lamp, and the objects around your computer (make sure they are neutral in color)! My suggestion for a light bulb is General Electric’s energy-smart, daylight, fluorescent bulb. Since I changed my bulb I have definitely seen more consistency in how my color is displayed on my monitor. Another key factor is to make sure you have consistent lighting conditions.
