In Photoshop you would cut out the figures, using for example the pen tool. Then once they are on their own layers apply the "outer glow" layer style using the desired colours.
For someone experienced with photoshop, and depending on the complexity of the figures, it would be a five minute job.
The takeaway for you here is to google "Photoshop outer glow"
