difference between ryegrass, tall fescue and KBG??

[taprlawncare]

I'm having trouble identifying the difference between the three. These are the main grasses that grow in my area, and while I think the majority is rye grass, I would like to be able to tell the customer which type of grass is growing in their yard. Any way of determining which is which?

Please learn how to search, this is really simple stuff.
