Some browsers limit the number of colors per image to something less than 256, but the color count is cumulative so for example if you had a color driver/card that supported 256 colors you would reach the limit with 5 gif's using 50 different colors each. By using colors from the same palette in each gif you can have more images. Fonts, buttons, background ... colors used by windows are included in the count.
In general the fewer number of colors you use to get the desired quality the better. Since gif images include the color palette as part of the image, limiting the colors will also limit the size of the gif and avoid excessive download delays.
Other applications can change the Windows color map affecting what you see in your browser window. Maximizing the browser window to cover the whole screen may solve this problem.
If you select a color that is not one of the standard ones some browsers will dither the image (See Images under General Preferences in Netscape). This will mix several colors to try and match the desired color but will take longer, so it is better to use one of the standard colors.
When using a graphics package to create images you may have to load the correct color palette to get colors you want. Even though your system is set to support 64K colors a given application may only have a 256 color palette it can work with. The better graphics programs allow you to change the default color palette.
Note: If you select Colors from the General Preferences dialog in the Options menu on Netscape 3 you will get the 48 color palette shown in the Windows colors section below. This comes from the windows color manager and is different from the Netscape palette below. Confused yet?
Following is a color cube representing the resulting 6 * 6 * 6 = 216 colors.
Other 216 coler lists at the right side of the Netscape page and here.
Netscape on UNIX may use a 5 value 5 * 5 * 5 = 125 color cube depending on the verson of netscape and other colors in use at the time. There is an example of it at http://kbs.cs.tu-berlin.de/~jutta/ht/cgrid.html
