I am trying the simulation for droplet solidification over substrates. The setup condition is given below.
droplet ejecting from the nozzle at 1000K and substrate gave to 300K. region 1 patched to molten metal volume fraction 1 and region 2 patched to air volume fraction 0.

Problem:
When the droplet reaches the substrate it starts solidifying and becoming blue in liquid fraction because the temperature comes to 300K. then somehow it merges with the air domain because that is also blue. I want to ask that is there any way that the air domain can be made colorless or transparent so the proper droplet shape can be seen.

Please Reply.
Thanks in Advance.
