Does mycelium turn blue agar orange?

I made a batch of plates that I transferred from clean growth plates where the same agar recipe was used in both. I used blue food coloring, but as growth happened on the new plates, the blue turned to orange as the mycelium grows. Does the mycelium eat the blue or is a competing contam?

Here are some of ones that started blue and all the blue is gone now. I did some transfers even with the orange and sure enough orange is starting on the new blue plates.

I believe mycelium can eat through food coloring...might be whats happening here since the coloration only changes when in colonized areas

It turns my green agar kind of yellowish. Pretty useful actually. It gives me an idea of how old the plate is with just a glance.

Thank you all, I was worried as the first plates that were streaked with spores didnt do it and now all of them are doing it!!!
