4. [gradient bar.py Gradient Bar In the picture above you will see a gradient bar. Gradients in computer graphics typically show a color progression. The example above is a progression of the green intensity from O to 255, with red and blue remaining at intensity O through the progression, spread across six rectangles. When you see graduated colors on your computer they are often created using this technique: having thinner and thinner rectangles makes a smoother gradient progression. For example, the gradient below is a green progression through 64 rectangles: Gradient Bar
