How to make a circle color spectrum in Illustrator
So you want to make a color spectrum like this, using Illustrator? Here is how you can do it.
Start by making a new document in Illustrator. The size does not really matter because Illustrator is resolution independent. I prefer to have my document in RGB colors because it gives me the freedom to move it over to diversity of different color profiles later on. Besides RGB has wider color spectrum and thus brighter colors.
