What is this 4x4 board with black and white sided, numbered pegs?

Question

I found this little boardgame but cannot figure out what it is. Hopefully you can help me?

Can you describe how the pegs are numbered? Does each peg have the same number on both ends, and how many of each number are there? — Ilmari Karonen, Mar 13, 2019 at 10:32

It's a "My First Sudoku / Child Sudoku" puzzle (a 4-number version of the usual 9-number pencil puzzle).

See for example this Etsy listing.

Is there a reason for the different coloration of pegs? Or is it just aesthetic?

You use one color to fill in the given/starting numbers of a puzzle. Then you fill in your solution with the other color. That way you know which pegs you can't change if you make a mistake and need to backtrack / change numbers.
