Using this technique, a developer does not specify any foreground or background colours. The consequence of this is that the user sees all the content in the default colours configured on his/her system (browser settings and possibly high-contrast colour scheme on his OS desktop). So you basically defer the responsibility for sufficient contrast to the user (or whoever configured their computer). As soon as you define a foreground or background colour, you are not using technique G148, and you need to look at http://www.w3.org/TR/2008/NOTE-WCAG20-TECHS-20081211/G18.html and test each foreground-background combination (including every link state - hover, focus, active, ... - and, if applicable, different states in form controls (for example, some developers change the background colour of a control on focus)).
