Raindrip

We have an irrigation system Raindrip, and we have a bunch of those things you put on the pip great for connecting to the pipe that goes to water the plant. They are different colors, but we do not know what color you can water less, and allows more information. Please help me and tell me what colors do what! Or give me a link that tells me! thank you very much!
