Web safe colour:

'A hex triplet is a six-digit, three-byte hexadecimal number used in HTML, CSS, SVG, and other computing applications, to represent colours. The bytes represent the red, green and blue components of the colour. One byte represents a number in the range 00 to FF (in hexadecimal notation), or 0 to 255 in decimal notation.'

"Computers monitors were not always the fine upstanding displays we know today. For a long time many monitors could only display 256 colors. When a color was used in an image that was not available on the monitor, a different replacement one had to be used. This was either the closest color or a dithered color which was slow to render but could look better. In a bid to make a standard palette of colors which were safe to use on monitors capable of showing 256 colors, a set of 216 colors were chosen and these were known as the web-safe colors. These days, modern computers generally have at least 16-bit color and often 24-bit color, which allows millions of colors to be displayed. Even modern phones, iPods and tablets can display more colors than the monitors of the early 90s, so there really is no need to stick with the web-safe palette anymore (unless you’re working for a client with a REALLY old computer who insists everything looks good on it). Today it’s more important to look at the contrast in your images rather than how many colors are used."
Web safe fonts:
'When a web page loads, the browser is told to write text onto the screen using a specified font—one that is stored on the computer that the browser is running on. Therefore, if the web page’s code is calling for a font that a user does not have installed on their computer, it won’t show up! What that person will instead see is a default font, which might look a little ugly.
Now you might be wondering why this will happen so often if there are so many fonts installed on your computer. Well, here’s the problem: the two most widely-used operating systems—Windows and Mac OS X—each come installed with a different set of fonts.'
