To do this, perform the following steps:

1. Run the following lines of code in the REPL:

>>> from adafruit_circuitplayground.express import cpx
>>> cpx.pixels[0] = 0xFF0000

1. You should see the first NeoPixel turn red. Run the following code to retrieve the color value of the first NeoPixel:

>>> cpx.pixels[0]
(0, 0, 255)

1. Run the following code to set the next two pixels to green and blue:

>>> cpx.pixels[1] = 0x00FF00
>>> cpx.pixels[2] = 0x0000FF

1. Use the following code to set the fourth pixel to yellow:

>>> cpx.pixels[3] = 0xFFFF00

1. Use the following code to display the integer value for the color blue, and then set the next pixel to the color blue using this integer value:

>>> 0x0000FF
255
>>> cpx.pixels[4] = 255
