The crimson-hued wallet-friendly phone is on sale from Google in Britain, Australia, Canada, France, India, Italy, Japan, Korea, Spain, and the US. Both the 16GB and 32GB models come in red, the 32GB version costing £339.
The red version may just be the start of a rainbow of colours for the 5-inch smart phone. Recent leaks, if real, suggest the Nexus would also be available decked out in rich dark red, orange, yellow, green, blue and purple colours.
If you already own a Nexus 5 smart phone or Nexus 7 tablet and you fancy a new look, there's currently 25 per cent off a selection of cases, sleeves and bumpers for both phone and tablet on the Google Play store.
