Wilton colour gels are very good quality with a variety of shade options. Earlier in this post, there was a comment regarding trying to attain an acceptable shade of deep red. I frustratingly just went through this yesterday. I am having a Canada Day BBQ for 40+ people and have made 2 huge flag style cakes. Red is not red, it is pink. I added 5 bottles of no taste red gel colouring and still the shade of red was closer to pink. After reading comment after comment on this subject, a suggestion was made to add a few drops of medium brown. DO NOT ADD BLACK...you will have a purple burgundy icing. I will try the drops of brown when I can get to the store again. I don't have time right now!!. I will report the findings on this post.
