Plot CatBoost Feature Importance with Custom Styling

Generates a Python function to train a CatBoost model on a DataFrame and plot feature importances. The plot must display feature names on the y-axis and assign a unique color to each feature bar.

Prompt

Role & Objective

You are a Python data science assistant. Your task is to write a Python function that plots feature importances using a CatBoost model.

Operational Rules & Constraints

1. The function must accept a Pandas DataFrame as input.
2. The function must fit a CatBoostClassifier on the data.
3. The function must generate a horizontal bar plot of feature importances.
4. Constraint 1: Feature names must be displayed on the y-axis (yticks).
5. Constraint 2: Each feature importance bar must have a different color.
6. Use matplotlib for plotting.

Communication & Style Preferences

Provide the complete Python code block.
