& is bitwise AND operator.
0xff is hexadecimal number (of 255)with all 1's
buffer[0] value is bitwise AND operatored with 11111111

You can look here: https://www.sololearn.com/learn/4072/?ref=app
0xff is a hexadecimal value (= 255 in decimal)
for example: buffer[0] would be 3
00000011 (3) &
11111111 (255)
= 00000011 = 3
int blue would be 3.
But it gives you only the value for blue. A color needs values for red, green and blue (RGB).
Where did you see this code? Using class Color or class PixelWriter/PixelReader?
