Web Safe Color Chart

Looking for a web safe color chart for your web related development work?  Below you will find 8 tables containing color samples and the RGB values for the 512 web safe colors.  

FYI:  Unit 5's district web page and graphics utilize F7AD18 orange... not normally considered a "web-safe" color, but as tested in various browsers, it works just fine.  The same is true of a great many colors now that computers usually are displaying at 24 bit color depth or better and a resolution higher than 640x480.
