Name

green()

Examples
c = color(20, 75, 200)  # Define color 'c'
fill(c)  # Use color variable 'c' as fill color
rect(15, 20, 35, 60)  # Draw left rectangle
greenValue = green(c)  # Get green in 'c'
print(greenValue)  # Print "75.0"
fill(0, greenValue, 0)  # Use 'greenValue' in fill
rect(50, 20, 35, 60)  # Draw right rectangle
Description Extracts the green value from a color, scaled to match current colorMode(). The 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 understand, but it is slower than a technique called bit shifting. When working in colorMode(RGB, 255), you can acheive the same results as green() but with greater speed by using the right shift operator (>>) with a bit mask. For example, the following two lines of code are equivalent means of getting the green value of the color value c:

r1 = green(c)  # Simpler, but slower to calculate
r2 = c >> 8 & 0xFF  # Very fast to calculate
Syntax

Parameters
rgbint: any value of the color datatype
