Mycelium eating food-coloring in agar plates?

So I’ve used various colors from a few different brands of food coloring to color-code my agar plates and I’ve noticed that sometimes the coloring will get lighter or disappear altogether under the mycelium and it seems to happen especially when I work with vigorous strains. I’ve always assumed that the mycelium must be “eating“ the food coloring, which is obviously designed to be edible — is that what is happening? Have any of you experienced this? And if so are there any brands that seem to hold up better? The most recent brand I used seems to be particularly prone to it and I'm miffed because I really like the color palette lol
Here's some fresh plates and then a recent multispore plate illustrating the color-change I'm talking about

Are you using the gel colors? I currently am using those and I find that Cubensis will eat the coloring like blue and orange but other species of fungus seem to not really affect the color of the plates. It must be pretty tasty to them or something.

Yes. Cube myc loves to eat up my food coloring. This behavior amuses me so I just laugh and shrug it off. But I’ll report back if I notice any colors or brands that the myc seems to consistently eat or avoid

I’ve noticed cube and oyster mycelium eats it up really quickly, but my ps. cyans don’t seem to be affecting the colors at all.

myc has to eat colors. how else are you supposed to see colors when you eat the shrooms?

Not sure exactly what gel colors are but the color in the pics is from some fancy confection colors for making fancy bourgeois cakes

Interesting. I've noticed my cubes definitely like some colors more than others -- blue particularly. But not every brand of blue, they're picky lol. And cyanescens myc seems to have the same taste as cubes IME

Try getting the myc to grow colored fruits. Imagine a bag of skittle-like mushrooms in all colors of the rainbow.

All cubensis strains I've used so far were eating my blue coloring

If I was going to try to do that, I'd probably introduce the colored water either to the bulk substrate before spawning or during bottom-watering. That'd be interesting if it worked lol

Blue will disappear pretty quickly.
I make my own now with grain water and no color. Need backlight to see it properly but I prefer no color.

I seem to have great success with blue agar not losing it's color. I use 'First Street' brand from Smart & Final stores. The color I have seen fade out the most is black.
