McCormick Culinary Blue Food Coloring, 16 fl oz - One 16 Fluid Ounce Bottle of Blue Food Coloring Liquid to Add Color to Cakes, Cookies, Icings and Fillings

I needed primary colors to dye wood blocks for use by children. This is the only product that has enough volume to allow for use when making multiple products or dying not so small pieces. It worked well. The colors produced were vibrant and stable, when mixed with vinegar. Highly recommend this product for hobbits/woodworking use if you need a non-toxic dye.

Great item great color

Works as a great alternative to weed killer dye at a fraction of the price . About a few table spoons of this dyes a 2.5 gallon jug i pour into my 4 gallon backpack sprayer so I can see where I sprayed when doing a driveway

It is blue food coloring as stated. It does what it is supposed to. This bottle is big!

I bought this so I could keep the water in my bird fountain blue. It works great and I'm very happy with it.
