Why Using Color Safe?

Color Safe is especially useful when providers like WordPress have started to impose stricter coding standards regarding accessibility factors since the mid-2010s. Designers must conform to various new standards when creating webpages, templates, plugins, and themes, especially regarding readability.

What does the new standard look like? One of them is related to contrast. According to Web Content Accessibility Guides 2.0, the minimum contrast ratio must be 3 for large text and 4.5 for the smaller one. This does not include choosing the right color palette. Using Color Safe makes it easier to determine the ideal contrast and palette.

By using Color Safe, you can find various palette alternatives that conform to accessibility standards. Simply click on each resulting color square to choose the most ideal one. You can also use the Start Over button to calculate different design elements.


Following the accessibility standard is mandatory for web designers. Color Safe is a simple tool that streamlines web designers’ works by reducing the guess works. With simple calculation steps, you can find the right palette and immediately adjust the webpage you are working on.
