SK Contrast is a free Chrome add-on developed by Stefan Kuip. It falls under the category of browsers and specifically belongs to the subcategory of add-ons and tools.

The main purpose of SK Contrast is to help users select a part of the viewport and compute the maximum contrast ratio. This can be useful for web designers, developers, and anyone else who wants to ensure that their content is accessible and readable for all users.

The latest version of SK Contrast, v1.0.7, includes improvements such as using shadow root to prevent style mixture, showing more color in a grid with contrast values, and an improved color selection process.

Please note that there may be a slight deviation in the contrast ratio due to the application of a monitor color profile when capturing the screen. However, this can be counteracted in Chrome by changing the chrome://flag 'Force color profile' to sRGB.

SK Contrast is a valuable tool for those who prioritize accessibility and want to ensure their content is visually clear and easily readable.
