Which of the following turtle methods affect the color of a turtle drawing? select all that apply.

Class that represents a Logo-style turtle. The turtle starts off facing north. A turtle can have a name, has a starting x and y position, has a heading, has a width, has a height, has a visible flag, has a body color, can have a shell color, and has a pen. The turtle will not go beyond the model display or picture boundaries. You can display this turtle in either a picture or in a class that implements ModelDisplay.
