Colour
There are 216 web-safe colours that will be reproduced exactly the same on every screen. These originate from the 256 colours that were capable of being displayed on 8-bit screens. The 216 colours are expressed in hexadecimal code, which is a hashtag followed by a series of six numbers or letters.
Using CSS allows you to specify an RGB colour using the colour codes from photoshop and illustrator etc etc, but if you choose a non-web-safe colour and the page is displayed on an older device, the colour may not appear the same.
Fonts
You should use standard, web-safe fonts so that the page will look consistent across all devices. Choosing a font family gives you a first choice font to use, then if that font isn't installed on a particular device, it uses the font you specify as second choice, and so on and so on.
CSS allows you to upload fonts on your website so your first choice font will always be available for use. This font must have a free distribution licence though, as uploading it to your site makes it downloadable.
