Coolors contrast checker

It’s amazing how much something simple—like thoughtful color choices—can improve the accessibility of your courses. Strong color contrast makes course elements easier to read and interact with. And considering how your design could be perceived by learners with different types of color blindness can help avoid visual miscommunication.These days there are a wide range of online tools that can help you check how accessible a color palette is. But it can still take some fine-tuning to ensure your color selections are most effective. To help speed things up for you, we’ve created this download with five accessible color themes built right into the Storyline 360 file.Created with the help of Contrast Grid and Coolors, these themes use high-contrast colors that learners with color blindness can easily distinguish from one another. In this file, you’ll also find a table for each theme that outlines which colors can be used together while maintaining a sufficient contrast ratio.Here’s how to use the recommendations from the table to guide your design choices:Using text on a background? Choose any pairing listed as Pass.Is that text 18pt or larger? Your options broaden to both Pass and Large Text.Are you placing two colors next to each other? You can also use combinations listed as Pass or Large Text.Because design needs can vary, you’ll notice two approaches to the theme accent colors. Some alternate between light and dark colors, making them a good fit for content that features graphs or other tightly spaced design elements. Others use a gradual color shift, offering more options to display text on, but requiring space between each design element. Just choose the type that works best for your situation. Like a palette but need a different color order? It’s easy to edit and rearrange the theme. And if you want to swap in some different colors, Contrast Grid and Coolors can help check that your new picks are still accessible.Explore this project.

Learn moreGuide to color contrastYou can trust our contract color checker or you can read this guide to learn more about accessibility standards.What is color contrast and why should you care?Color contrast is the difference in light between two colors. In web and graphic design, it typically describes the relationship between text color and its background color.High contrast makes the text easy to read, while low contrast can make it difficult or impossible for some users to discern the content.How to measure color contrastColor contrast is typically measured using a contrast ratio, ranging from 1:1 (no contrast, same color) to 21:1 (highest contrast, black text on white background or vice-versa). The color contrast ratio represents the difference in luminance or brightness between two colors.The contrast ratio is calculated using the following formula:(L1 + 0.05) / (L2 + 0.05)Where L1 is the relative luminance of the lighter color and L2 is the relative luminance of the darker color.WCAG contrast guidelinesWe recommend adhering to the WCAG (Web Content Accessibility Guidelines) color contrast guidelines for web and graphic design.WCAG 2.0 brought the use of the minimum contrast requirements (AA level), which became even more stringent with WCAG 2.1 in 2018. The subsequent WCAG 2.2 and the upcoming WCAG 3.0 don’t bring anything new in the context of color contrast.WCAG 2.0WCAG 2.1Small text4.5:17:1Large text3:14.5:1Non-text content/3:1Whenever possible, you should adhere to the WCAG 2.1 guidelines, with WCAG 2.0 guidelines being the mere minimum.In our contrast checker tool above, you will see a green color when you meet WCAG 2.1 guidelines and a yellow color for WCAG 2.0, while you’ll get flagged with red if your color contrast meets neither.Small textSmall text is defined as any text below 18 points or 14 points (pt) if bold.

Easy. Here are some tips to help ensure your graphs and charts are effective:A) Use Clear and Concise LabelsOne of the most important things to keep in mind when creating graphs and charts is to use clear and concise labels. Avoid using technical jargon or abbreviations that your readers may not be familiar with. Instead, use simple, everyday language that is easy to understand. It’s also best to keep your labeling simple and straightforward, using colors that contrast with each other to make it easy for your readers to distinguish between different data sets.For example, if you’re creating a bar graph to compare the sales of different products, you might use different colors for each product to make it easy for your readers to see which product is which. You might also include a legend that explains what each color represents.B) Choose Appropriate ColorsChoosing the right colors for your graphs and charts is also important. You want to choose a color scheme that makes it easy for your readers to distinguish between different data sets, but you also want to make sure the colors you choose are visually appealing and not too distracting.One way to choose colors is to use a color palette generator, such as Coolors or Adobe Color. These tools can help you create a color scheme that works well for your data and is visually appealing.C) Maintain Consistency in DesignAnother important factor to keep in mind when creating graphs and charts is to maintain consistency in design. This means using the same fonts, colors, and layout throughout your graphs and charts to make it easy to comprehend the data.For example, if you’re creating a series of line graphs to show the growth of your business over time, you might use the same font and color scheme for
