Does it count if you know the color is in the picture but you can't quite see it?

I don't know, but I feel like it should because what I saw tonight is the first one I remember seeing since I was 4 or 5 years old. That's right, my #ColorChallenge photo is this:

🌈 A Rainbow! 🌈

Here it is, off my porch and definitely containing #indigo.
