I think that orangish look is more a function of me holding the frag super close to the surface and it being hit with much more "blue" than normal causing fluorescence.
Here's a picture of the colony I just snapped, unfortunately it's a side view with not much detail inside, the larger frag has a more yellow/lime green center with a hint of orange, the smaller ones definitely have orange. Halides just went off so no top-down photo.
