a fixed point is a function input that does not change when a specific function is applied. for example, if you have a funcrion that takes a color and returns the gray scale value of the color, all black/white/gray colors are the fixed points since thw gray scale value of black is just black, and white is just white, etc

fixed point itteration is a method for finding a fixed point where you throw any point into the function, the output back into the function repeatedly until it stops changing.
