What type of food coloring for agar? 1

Guys,
I just started working with agar. I've seen photos of agar plates in which the agar has been dyed various colors. I like how the mycelium is more visible against the colored agar background.
I'd like to buy some type of liquid coloring to mix with my agar. Does anyone have any recommendations? I found these two brands:

The Trucolor contains glucose. Is it potentially unwise to add additional glucose to the agar mix?

The PME doesn't contain any glucose. Is it preferable?
Please tell me what brands have worked for you.
Thanks,
Tom

Any dark color would work. But green might not be the best because trich, a common mold, sporulates green.

I just did some pitch black plates! They look bad ass. I cannot wait to see the myc contrast on them. I am going to do some transfers from a few clones tonight on them

Well myc is white. Take a wild guess what is most contrasting to white.
Granted, you can't see through the agar but I've never learned anything from doing that anyways personally but I'm sure it's useful in some cases.
Here's a couple of mine.

Weird. My McCormick neon works great!
I don't think any food coloring should be killed by heat, it's meant for food for crumb sake.

I really like making bright blues and green to look at. The black is still functionally my fav and my new regular plate.
