Does anyone have experience with coloring the shells with natural color sources. Turmeric, spirulina...?

I am new here and wanted to introduce myself. I made decorated sugar cookies for many years and when my daughter was diagnosed with Celiac disease, I wanted to find a sweet treat she could eat. My son was diagnosed a few years later. I’ve been making macarons since 2020. My daughter got married last year and I made 454 macarons for her wedding. I enjoy trying new recipes and look forward to learning and sharing.

Any tips or tricks are greatly appreciated! Can’t wait to try out this new recipe for macarons!

I recently tried macarons for the first time and instantly fell in love. I’m a small time home baker and would love to add this to my things I bake. My first try with these was a recipe I found on tick tock. They came out looking okay but was hollow. I tapped the top of all of them and they cracked 😬😬 I hope this community can help me perfect and achieve my goals with this new item :)

Tried the recipe for the first time today, here is how they came out. What do you think?
