Ok. This was tough because my curls are not very photogenic. Most of my pics looks like a big blob. LOL.
I'm including one pic of my hair when I was relaxed because it shows what my natural color looks like in full sunlight. This will give you an idea of why most people didn't notice when I started to use henna because it only shows up on my grays. For recent pics of henna+indigo I took one in indoor light and one in outdoor. I think gray coverage in the front was excellent when I put indigo over the henna but my natural color hair didn't become super dark maybe because I didn't apply the indigo very thick. Anywho, I'm happy with it.
