color.theme.info() returns a data frame listing all available color themes.
color.theme.env() provides direct access to the environment where the color themes are registered.
Value
color.theme.info() returns a data frame with columns "name", "source", and "type".
color.theme.env() returns the environment currently used as the default theme registry.
Details
These functions provide tools for inspecting the color themes available in the current R session.
color.theme.info() is the primary user-facing function for discovering themes by name, source, and type.
color.theme.env() is an advanced function that returns the environment currently used as the theme registry.
It first checks for a user-specified environment via getOption("midr.color.theme.env").
If this option is NULL (the default), the function returns the package's internal environment where the default themes are stored.
