The white insides of the cup is a factor. I saw no effect with clear
container. I saw some effect with white insides but not as bright as
effect in video. Perhaps I need a brighter shade of red.

I had it in mind there was backscatter from suspended particulates.
I tried with very dilute milk - but my straw was not boldly colored
enough to be convincing.

Have you tried putting a blue object in the lemonade?
The effect shown in video did not occur with the yellow food dye I used.
The part of a blue object that is in the water does appear green.

My daughther, who loves science, showed me this cool phenomenon the other
day and I had to put a video of it online. She was putting a red straw into
yellow lemonade and the effect was far bigger than I would have imagined.
To the eye, it was even bigger than in this video. It almost looks fake.
We also tried it with a different type of lemonade and it still worked.
Go to this link and it's the second video down:

I've added about 8 more clips to that page as well.
