Ok. for the family album....but I don't see the colors you're referring to in this image. Perhaps an even more limited depth of field would help blur the distraction of the background?
Complementary colours are pairs of colours that contrast strongly when compared to each other.
The colours in this photo are so desaturated that the effect of complementary colours is lost. Your image demonstrates a duotone effect rather than the effect of complementary colours.
Check some of the forum discussions on complementary colours for suggestions on using colour for contrast.
