Choose_Color.py

#Define colors
rgb9 = (0,255,0) #green
lcd.setCursor(0, 0) #Set the position of cursor
# print the number of seconds since reset:
lcd.printout("Waveshare") #Print the string
lcd.setCursor(0, 1) #Move the cursor to second row.
lcd.printout("Hello,World!")#Print the string
lcd.setRGB(rgb1[0],rgb1[1],rgb1[2]); #Set the back light

Discoloration.py

t=0
while True:
 
   r = int((abs(math.sin(3.14*t/180)))*255);  #RGB changes as time goes
   g = int((abs(math.sin(3.14*(t+60)/180)))*255);
   b = int((abs(math.sin(3.14*(t+120)/180)))*255);
   t = t + 3;
   lcd.setRGB(r,g,b);#Set the RGB data again.
# set the cursor to column 0, line 1
   lcd.setCursor(0, 0) #Set the curson to the first row.
# print the number of seconds since reset:
   lcd.printout("Waveshare")#Print the string
   lcd.setCursor(0, 1) #Set the cursor to second row
   lcd.printout("Hello,World!")#Print the string
