Python Color Constants Module
When working with colors in programming languages like Python, having a set of predefined color constants can be incredibly useful. This is especially true for projects involving graphics and game development, where consistent color usage is crucial.
In this article, we'll take a closer look at creating a Python module that houses color constants, specifically focusing on the 255-color palette with white as one of the colors. We'll explore how to store these constants in an OrderedDict and extend the Color class to include a method for getting the hex formatted color.
Storing Color Constants
To begin, let's create an OrderedDict to store our color constants. This data structure allows us to easily access and manipulate our color values. Here's the code:
```
color_constants = OrderedDict()
```
Next, we'll define our color constants as named tuples:
```
Color = namedtuple('RGB', 'red, green, blue')
```
With these in place, we can start populating our color constants.
Extending the Color Class
To make working with colors more convenient, let's extend the Color class to include a method for getting the hex formatted color. This will enable us to easily convert our RGB values into their corresponding hexadecimal representations.
Here's the updated code:
```
class Color:
def __init__(self, red, green, blue):
self.red = red
self.green = green
self.blue = blue
def get_hex_color(self):
return '#{:02x}{:02x}{:02x}'.format(self.red, self.green, self.blue)
```
Now we can create color objects and easily retrieve their hex formatted values.
The 255-Color Palette
As mentioned earlier, we'll be focusing on the 255-color palette with white as one of the colors. Here's a breakdown of the colors:
