Web-Safe 2000

In some situations, like when you have vast expanses of flat color, it makes sense to stick to web-safe values. Similarly, if you have a GIF logo and you don't want the main parts of the type to go speckled on 10% of the monitors out there, then make sure that you choose a web-safe color for the body and background of the type. Don't try to force the whole GIF to web-safe. Anti-aliasing type has the effect of generating about 20 intermediate hues between the foreground and background colors, you can safely reduce the number of intermediate colors by saving the GIF at a lower bit-depth.

Restricting your palette

Restricting your palette is not a bad idea. Many of the most famous painters restricted their palettes to a few oil paint pigments. This was more of a practicality than an aesthetic judgement. In earlier times, artists had to grind their own pigments from locally available raw materials. The broad spectrum of paint colors available today is largely based on synthetic, chemically derived pigments that just weren't available until recent times.

Monitor color depth

Virtually all cathode ray tube-based computer monitors are capable of displaying an infinite number of colours. Each of the Red, Green and Blue components can go from nothing (black) to full brightness just as if you turned a brightness knob on the monitor's control panel. Cathode ray tubes are analog devices and the brightness of the colors on the screen is proportional to the voltages applied to the cathodes.

Depending on the type of surfer your site is aimed at, you will have a pretty good idea of how much you have to religiously adhere to the web-safe palette. Business people tend to have less well specified computers than home users. If a computer is used mainly for word processing or spreadsheets, high color depths and sound capabilities are not very important. Design accordingly. Emotive aspects of color.

Nikon Coolpix 950

I've been a Nikon fan for a long time and have had a number of Nikon F-Series 35mm SLRs and I also have a Nikon SuperCoolScan 35mm scanner which is excellent. When it came to choosing a digital camera, I knew I couldn't go far wrong with a Nikon. The Nikon COOLPIX 950 is a progression in a line of similar digital cameras that have a distinctive 'twist-to-use' format. The lens, viewfinder and flash are housed in one section whilst the other holds the electronics and the TFT LCD monitor.
