Better to be (web) safe than sorry
October 30th, 2007 
It’s quite a headache to find out that after spending a lot of time deciding what your site’s colors will be, that they may not show properly on some systems. This happens when the system does not recognize the color value and can often result into undesired dithering. So how can you be sure then that your chosen color will be displayed correctly on different systems? That’s where WebMaster Toolkit’s free Websafe Colour Tool comes in.
The tool allows you to get the nearest match of your chosen color using the 216 websafe color palette. With this tool, you can check whether your chosen color will display correctly on computers running a 256 color palette. It ensures that the colors you have chosen or would choose for your site will be consistent when displayed on any browser or system. Using it is as simple as keying in your chosen color value. If the chosen color is a websafe color, it will return the same value. If not, it provides you with the color value of its nearest match.
By knowing what colors are considered web safe, you are sure that your web pages will show off their true colors.
Knowledge of the hexadecimal values of colors is needed to make use of the tool. Basic HTML is also needed to apply the colors provided by the tool to your web pages.
