All she needed to do was substitute the green for the red :). That’s what I did to produce a blue velvet cake for DH’s birthday one year.
And it was just after I hit Post that I spotted the word “mix”. NM. (embarrassed look)
They’re onto something with the use of blue food coloring. When one of the office ladies turned 40, someone brought in a cake covered in what appeared to be black decorations… The bakery had achieved this color through the excessive use of blue food coloring. People were cheerfully discussing their bright green leavings the next day.
If you’ve ever used a juicing machine on beets, that has the same effect, only it dyes your urine also. Bright pinkish red pee will get your attention if you’re not expecting it.
I was given a purple cauliflower which I thought was pretty cool. Hubs didn’t like it on sight. I steamed it at dinner and it turned blue. Hubs ate a bite, agreed that it tasted like normal cauliflower and left the rest on his plate.
The water in the steam pan was a lovely indigo, so I tried dying a cotton tea towel, which didn’t work at all.
Mom and I ate most of the cauliflower and didn’t notice odd colored output. We feel ripped off.
Fun fact: Take any naturally-occurring dark red or purple vegetable or flower (e.g., red cabbage or purple flag iris), boil it to get a reddish-purplish liquid. Put anything acidic into it (e.g., lemon juice) and it turns red (or redder). Put anything basic into it (e.g., soap) and it will turn more bluish. It’s a naturally-occurring acid/base indicator.
From the OP: “Turn your Poop Blue!”
How about: “Turn your Poop Rainbow!”
The story was told (this was before my time) that our Airedale did this. She got into a box of crayons and ate them. Rainbow poop ensued.
But this is actually surprising in some ways, and I wonder if it was that the purple and green were particularly vivid tones?
I mean, I eat out a lot, and it’s pretty common for one or more of the condiments or sides to be a slightly unusual color due to containing pesto, or beetroot, or whatever. As long as it’s a somewhat dark or earthy color, it doesn’t trigger any kind of revulsion.
I wouldn’t buy the funny colored ketchup, but just because I have no reason to. No reason to confuse things, if the taste is apparently the same.
I’m no Andrew Zimmern of Bizarre Foods fame, but I’m a decently adventurous eater by mere mortal standards.
Green or blue ketchup is fine with me. But for some reason purple potatoes are a struggle. They taste fine, the texture is fine, they smell fine. But something about them screams Oooh! That’s Not Right.
And yet, ironically, there ARE purple potatoes that come that way naturally, without any dye. My wife regularly prepares spiced mini-potatoes that include purple ones among the mix.
Those are exactly the potatoes I’m weirdly uncomfortable eating. Despite knowing they grow that way and I’m the guy who bought them, cleaned them, cut them, and cooked them. Other blue/purple food is fine, such as blueberries, eggplant skins, some grape cultivars, etc.
Like I said, it makes no sense.
I suppose there are folks who enjoy the flavor of oysters and the ceremony of eating them, but not so much the texture. This may be more of the same.
I was in a remote rig site somewhere in Patagonia and the camp service team had a lot of picked beetroot. I ate a lot, then later nearly went to the medic as I thought I was peeing blood . Really quite disturbing.
I played a trick on my grandkids years ago. Mother’s cookies sells frosted animal cooking around the 4th of July, they are colored blue and pink. I bought 3 bags of the cookies and removed all the pink cookies. I then let them chow down on all the blue cookies they wanted. The next morning my daughter called and wanted to know what I fed the kids. One of the twins went to the bathroom that morning and left some fluorescent green poo in the toilet. This upset her, it wasn’t the normal color. A short while later Blake, the youngest did the same thing. I told her about the blue cookies. The other 2 grandkids left the same that day. After that I could get 3 of them to eat the blue cookies, Samantha refused, the bright green poo scared her.
Yeah I would avoid the red hues.
I once was taking a 12 hour drive, and forgot snacks. Stopped at a little gas station, and all I could find were those red dyed pistachios. So I bought a couple bags and spent a good deal of the trip eating them and sucking on the shells out aofboredom.
Next morning woke up and had a huge shock when it came out red as hell, I assumed I had some serious bleeding issues in my lower tract some where. I was actually getting in the car to head to the emergency room, when I noticed some of the shells in the ashtray and put 2 and 2 together.
Cute story. Thanks for sharing.
IANA parent and therefore IANA grandparent. But ISTM that half the fun of being a GP is using the grandkids to play tricks on their parents = your kids. Old age and treachery and all that.
Back in the olden days when I went to The Big U, I heard stories where chem major frat boys would invite the nerd math majors to a party. The punch bowl would be filled with some sort of noir-grape concoction, other drinks offered would be pinkish in color.
The next day would find Student Health Service packed wall-to-wall with math majors who swore they were dying!
Methylene blue is a dye which will stain urine blue.
Phenolpthalein is a dye that will give you the drizzling shitz. It used to be the active ingredient in ExLax.

Truer words have never been spoken!
Sometimes I just look at my daughter, I don’t need to say a word. Turn about is fair play.
Yeah, I see golden beets at the grocery store and wonder, what’s the point?
Our dog did exactly the same thing. Rainbow poop.
Various Burger King locations once (around 2012, I think) offered a special Halloween Whopper featuring a black bun. Many reports that customers noticed the effect on their digestive byproduct the next day.
