Muddiest point - wk 8 (I think)

Having gone over this a few times, I am wondering how one determines when to use the HEX color value or the RGB color value in a CSS?

h1 (background-color:#ooffoo)

h2(background-color: transparent)

p(background-color:rgb(250,0,025))

The example given on CSS instructional pages(above) uses both.
