Micro Fungi Photography

[mspear]

During routine diagnosis I happened to snap a few shots of
conidiophores growing on a selective medium that was a deep blue.  The
results were stunning.  Having a background added depth and contrast. 
The prosaic became art.

Anyone know what can be used to tint agar media strongly without
making it selective?  Or have I just been staring too long into
microscopes and lost it?
