Grey
Grey is the original PVC pipe color. According to the PPFA website, an industrial grey was the earliest PVC pipe color and it is still common. Like white, grey PVC pipe is often used for plumbing.
Green
Green PVC pipe is less common than other colors. While PVC pipe colors are not regulated for specific uses, green PVC pipes are often used specifically for sewage.
Blue
Blue PVC pipe is available for personal purchase and does not have a specific purpose -- it can be used for any PVC pipe need. Some manufacturers color their PVC pipe blue to make it stand out from competitors' products.
Yellow
Yellow, or similar colors such as buff, are not used for any specific purpose. They are available for consumer purchase for any reason.
Pink along with many rainbow of colors usually furniture grade PVC.
As by above consumed for any purpose based on strength and burst pressure. For plumbing you would want schedule 40 or 80 PVC. Which has requirement stamped on PVC piping.
Open this to find burst pressure ratings.

The lighter Class 200 PVC is fine for irrigation mainlines, class 120 can be used for lateral lines, but I wouldn't recommend it, it's pretty brittle. Schedule 40 is a bit of an overkill, schedule 80 is the thickness of fittings, way overkill.
Green is usually used in agriculture for lower pressure, high volume applications. White should not be exposed to sunlight.
Grey is commonly used for electrical conduit. So cutting into a piece of it is risky!
