Color Palette Generator -

Brief about script

• The app.py script creates a Flask web server that serves an HTML page (index.html) where users can generate color palettes.
• The generate_color_palette() function in app.py generates a list of random hexadecimal colors using the random module.
• The front-end (index.html) uses a form to capture the user's input for the number of colors, and the results are displayed using a simple CSS grid for visualization.
• Each color is displayed as a square with its corresponding hex code.

Issue no. - #887
