Possible double post- any hints or pointers on tinting this shade of blue? Customer wants this cake in buttercream ... Due tomorrow I have the crumb coat done now I need to figure out how to achieve this blue color
You can add very small amounts of black a little at a time to darken the blue to navy. Just be careful because it does tend to darken over time. So, add a little black until it's close to what you want then wait at least an hour or so and see if it's dark enough before you add more.
