The older, Classic version of Colour Contrast Analyser (2.5.x) also has a built in screen, web page, and file viewer that will allow you to see what the colors look like as a whole for people with various types of color blindness. Hexidecimal code for white is #ffffff, and for black is #000000. Hexidecimal code for color takes the format of an octothorpe (pound symbol) followed by six letters or numbers, two characters for red, two for green and two for blue. The hexidecimal color codes from the passing colors can be copied and used in Word or Blackboard Learn’s content editor. Hexidecimal code is typically how colors are designated in HTML. If your color choices don’t pass, there are sliders to adjust the red, green, and blue values to change the color to something that will pass, and suggested variations on the color. Colour Contrast Analyser will tell you the contrast ratio of your selected foreground and background colors, let you know if it passes WCAG 2.0 level AA and level AAA, and toggles into a mode that lets you see how people with different color blindnesses see your text against background. You can keep the application on your desktop or set a short cut for it within your Start menu in Windows to have easy access to launching it. This is a nifty tool and I recommend downloading and installing it! It contains an eye dropper for sampling colors on your computer screen, much like that of Adobe Photoshop’s color picker. It is a free download from The Paciello Group’s website. A stand alone application that will tell you whether your foreground and background color choices have enough contrast to meet WCAG 2.0 level AA or level AAA standards is called Colour Contrast Analyser. There are lots of color contrast analyzers available within various programs and as free downloads on the web. WCAG 2.1 has an additional standard (1.4.11) for user interface components and graphical objects that requires a contrast ratio of 3:1 against adjacent colors to pass level AA. The contrast ratio requirements are the same for WCAG 2.1 for level AA. A large print size is considered 14 pt (approximately 18.66 px) bold, or 18 pt (24 px) or larger non-bold text. Large print sizes, or large scale text can have a contrast ratio of 3:1. WCAG 2.0 guidelines require a contrast ratio of 4.5:1 between the foreground color (text color) and background color to meet level AA, for standard font size, e.g. Captioning and Transcribing Audio/VideoĤ5.
