Why Does My Red Food Coloring Turn Pink. Generally speaking acidic soil with a pH lower than 60 yields blue or lavender-blue hydrangea blooms. For this reason liquid food coloring has plenty of water in it.
Anthocyanins are known to change color at a low pH-value starting at around 3. Two because unlike all the other colors we have a very common color name for the pastel form of the color red. Doesnt take a whole lot.
Sorry to be the bearer of bad news.
It is because natural brands are usually in brown or greenish shades. It takes a LOT and I mean ALOT of red coloring to achieve red when using wilton. Yellow mixed with white is still yellow even if it is slightly diluted. Alkaline soil with a pH above 70 promotes pinks and reds.
