I made these monogrammed cookies for a communion. I mixed the round monogrammed cookies with decorated cross shaped sugar cookies. The colors for the communion were chartreuse and white so I tried my best to tint the royal icing the shade of chartreuse. It was a bit tricky because I had never made such a specific color before. I usually just make cookies any color that I mix up randomly. Luckily, I came across Sweet SugarBelle's wonderful royal icing color chart. For chartreuse colored icing, it said to mix 5 parts lemon yellow and one part leaf green, so I did. SugarBelle has many, many fabulous tips and is such a talented cookie decorator. I'm so glad I went searching for a way to make chartreuse colored icing and discovered her blog!
With my first attempt to make a "specific" icing color, I think it turned out quite well as my friend was happy with the results.
