That's why weighing out the amount needed for a certain color is helpful - it's more precise, so you minimize the possibility of running out and having to remix a matching color. Of course, if you weigh the icing to start and count the drops of coloring that went into it to create the original color, it's easier to replicate a color too. God bless the scale; more people should use them!
