Fantastico, I also made my wit with my lemonades, and other types of juices or refreshing drinks.
When I have prepared lemonades I have changed the color and decorum according to the color I put it.
In the market you find dyes that are used to decorate cakes.
Just add a few drops and there is the desired color.
When I have prepared the green tone in addition to the slices of lemon, I put some mint leaves, this enhances the style of the gastronomic presentation.
When I prepare with yellow, I add pieces of peach (damask).
And to be more original, I also add a few drops of the dye to the water that will make the ice.
If you allow me, can I post about that experience?
Respecting your idea, which is similar to mine. But I do not want it to look like plagiarism.
Health for your refreshing drink.
Congratulations for your post the projection of pink colors looks great.
