About

A very simple extension that displays two filled squares, one inside another, and allows the user via sliders to change the RGB value of the fill colour in each square.  

The Larger, or Smaller square is chosen via one of two radio buttons.

The Hex Value is also shown for the RGB colours of the square that has been chosen.

By having one square inside another it allows the user to see the contrast between two colours.

The extension is free of fees and adverts.

Privacy

The extension does not collect or process any user data
