Why color doesn't changed for the turtles?

I'm quite new to NetLogo and I want to use the below code to create a world of green and red circles, but the below code doesn't work with the color as it is only grey? any advice? 

to create_turtles 
  ca  
   ask patches  [ sprout 1 ]
  ask turtles [ set shape "circle" set color green] 
end

enter image description here

I just tried your code and it works just fine except it just create all green turtles (circles). If you want it red and green, I suggest you add some piece of code in the ask turtles command and may I suggest you to use the indentation style as well (usually NetLogo will do it automatically):

to create_turtles
  ca
  ask patches [ sprout 1 ]
  ask turtles
  [
    set shape "circle"
    set color green

    let chooser random 2
    ifelse chooser = 0
    [ set color green ]
    [ set color red ]
  ]

The let procedure is a local variable assigner and we let the value a random number of 0 and 1 (two numbers, hence the random 2, and primitive random always include 0 as first number).

In that example we ask the circles to randomly choose a number between 0 and 1. If it chooses 0 then it will set it color to green, otherwise red.

You can explore more about those primitives in the NetLogo Dictionary.
