Unusual blue color icing

[abchal]

My daughter is getting married and this is the cake she would like me to replicate. The question that I have is how to get this unusual blue base color. I have a variety of Wilton Gel food coloring colors but none of the blues match so I'm assuming that I will have to add another color but don't know which ones to try. Thank you for your help!

It looks like cyan to me. This can be made from blue and green, and maybe also some yellow.

Start with a white icing base and add very small amounts of blue and green. Adjust if needed with yellow. This a trial-and-error project, so plan ahead for 1 or 2 icing batches that are unusual due to color. Because it's your daughter's wedding, you will of course have planned well in advance for this.

To achieve the unusual blue color for your cake, start with your base blue gel color and gradually mix in tiny amounts of purple or green gel. Add these colors slowly and mix well until you reach the shade you want. It’s easier to add more color than to lighten it, so go slowly and test the color on a small amount of frosting first. This method should help you match the shade you need!
