The module name of Pillow is PIL to make it backward compatible with an older module called Python Imaging Library, which is why you must run from PIL import Image instead of from Pillow import Image. You can then store the loaded image in a variable like CatIm. To load the image, you import the Image module from Pillow and call Image.open(), passing it the imageвЂ™s filename. The camera adds 10 pounds (which is a lot for a cat).

You can find the full list of more than 100 standard color names in the resources at. Pillow supports a huge number of color names, from 'aliceblue' to 'whitesmoke'. You can also pass more unusual color names, like 'chocolate' and 'Cornflower Blue'. The color name string you pass to ImageColor.getcolor() is case insensitive, so passing 'red' вќ· and passing 'RED' вќё give you the same RGBA tuple. > ImageColor.getcolor('CornflowerBlue', 'RGBA')ДЇirst, you need to import the ImageColor module from PIL вќ¶ (not from Pillow youвЂ™ll see why in a moment). > ImageColor.getcolor('chocolate', 'RGBA') To see how this function works, enter the following into the interactive shell: This is why RGB values represent color in computer programs. When combining light (such as the light given off by your computer screen), red, green, and blue light can be combined to form any other color. However, the physics of light uses whatвЂ™s called an additive color model. This is why color printers have CMYK ink cartridges: the Cyan (blue), Magenta (red), Yellow, and blacK ink can be mixed together to form any color. This is known as the subtractive color model, and it applies to dyes, inks, and pigments.

In grade school you learned that mixing red, yellow, and blue paints can form other colors for example, you can mix blue and yellow to make green paint. TableВ 17-1 lists a selection of standard color names and their values.

Pillow uses the standard color names that HTML uses. After all, invisible red looks the same as invisible black. If a color has an alpha value of 0, it is invisible, and it doesnвЂ™t really matter what the RGB values are. White, the combination of all colors, is (255, 255, 255, 255), while black, which has no color at all, is (0, 0, 0, 255). This color has the maximum amount of red, no green or blue, and the maximum alpha value, meaning it is fully opaque. For example, the color red is represented by (255, 0, 0, 255). In Pillow, RGBA values are represented by a tuple of four integer values. If an image is displayed on the screen over a background image or desktop wallpaper, the alpha value determines how much of the background you can вЂњsee throughвЂќ the imageвЂ™s pixel. Images also have an alpha value to create RGBA values. A pixelвЂ™s RGB setting tells it precisely what shade of color it should display. These RGBA values are assigned to individual pixels a pixel is the smallest dot of a single color the computer screen can show (as you can imagine, there are millions of pixels on a screen). Each of these component values is an integer from 0 (none at all) to 255 (the maximum).

An RGBA value is a group of numbers that specify the amount of red, green, blue, and alpha (or transparency) in a color. Computer programs often represent a color in an image as an RGBA value.
