false-colour

The greyscale infrared pictures can be used to create colourful false-colour infrared pictures. The infrared picture (ir) is swapped into the red channel (r), whereas the original red and green (g) channels are swapped into the green and blue (b) channels, respectively (the original blue channel is not used):
