feat(colors): add function get_complex_color colored text in console

* This function allows you to print colored text to the console output.
* Use your own text and color to print a color message on the console.
* Choose from 255 available colors.

Usage:

Assigning function to variable.

```python
mds = get_complex_color
```

Printing colored text on the same line by function calling.

```python
print(
    mds(),
    mds('example text', 77),
    mds(text='more example', color=99),
    mds(color=187) + mds('-dev', 86),
    mds('check it', 196)
)
```

feat(colors): add function `complex_color` define color console variable

* This function should not be changed.

fix(colors): moved variable from `show_complex_colort` to new function
fix(colors): cleanup docstring
