pcolor VS spacy-altair-theme

In the case of the pcolor package (bootstrapped from the nbdev template), we can find an Altair (and seaborn) theme for personal use. This package contains color constants and various utilities, in addition to the typical function for the theme (pulsifi_theme). It also provides a utility function called setup_altair() that wraps up theme registration and activation.

Based on spaCy branding, we can find two themes in the spacy-altair-theme package. One of them is a monospaced version of the available base theme. In addition to a function for each of the themes (each function contains some constants and returns a dictionary with the configuration for the respective theme), we can also find three importable lists for the three types of defined color palettes. To use these themes, we just need to alt.themes.enable() the desired one, as these are alt.themes.register()ed when we import the package. As a final note, spaCy's blue has been replaced with a darker variant for color contrast purposes.
