experience. The food coloring pastes I have used, have always
had a color chart to reference to before I purchased the
paste. There are a number of different colors of red, which
one did you purchase? That is the only thing I can think
of which would affect your final color. What type of frosting
were you putting it in? I'm sure with all the input there
is on this site, we can help you get to the bottom of this
& solve the problem.
