Understanding SC 1.4.3 provides some good advice on the topic:
http://www.w3.org/TR/UNDERSTANDING-WCAG20/visual-audio-contrast-contrast.html
Basically, even though SC 1.4.3 does not require sufficient contrast in this situation it is advised to provide good contrast. This can be met a number of ways and using lines/halos etcetera is one method. As others have pointed out SC 1.4.1 Use of Color does apply to labels, line, patters, etc. would be needed to make the information visually accessible to people with color perception challenges. Once again there are many ways to meet each success criteria and some methods are better than others.
If the infographics contain a lot of text there could be a strong case for SC 1.4.5 Images of Text. I have seen some good examples of info graphics done up as text using CSS and images -- so in some situations the technology does allow for this.
