Name | ### green()
Examples |
    noStroke();
    color c = color(0, 126, 255);
    fill(c);
    rect(15, 20, 35, 60);
    float value = green(c);  // Sets "value" to "126"
    fill(value);
    rect(50, 20, 35, 60);
Description | Extracts the green value from a color, scaled to match current colorMode(). This value is always returned as a float so be careful not to assign it to an int value. The green() function is easy to use and undestand, but is slower than another technique. To achieve the same results when working in colorMode(RGB, 255), but with greater speed, use the >> (right shift) operator with a bit mask. For example, the following two lines of code are equivalent:
    float r1 = green(myColor);
    float r2 = myColor >> 8 & 0xFF;
Syntax |
    green(color)
