Mastering the Art of Color Contrast: A Guide to the DHS Color Palette Picker Wheel

When it comes to creating visually appealing and accessible designs, understanding the importance of color contrast cannot be overstated. The Color Contrast Analyzer (CCA) tool helps designers determine the legibility of text and the contrast of visual elements, such as graphical controls and visual indicators. To ensure compliance with Section 508 Accessibility guidelines, designers must adhere to specific requirements regarding color contrast and usage.

The Requirements

At a minimum ratio of 4.5:1, contrasting colors or shades are required for discerning between background and foreground content. Moreover, information conveyed through color must be provided in text displayed on the screen or by visual differentiation. In addition, color cannot be the sole means of conveying information, indicating an action, prompting a response, or indicating status.

The DHS Color Palette

The Department of Homeland Security (DHS) has developed its own color palette, which includes two official colors: Old Glory Blue and Old Glory Red. These colors are also the official colors of the United States. The DHS Color Palette is designed to ensure uniformity and strong brand recognition across all DHS components.

Using the Color Wheel

The image below demonstrates the correct usage of the DHS Color Wheel. The primary and secondary colors are indicated with a star, corresponding to a '50' value on the USWDS color wheel. Primary colors must be used in key design elements such as headings, features, etc., while secondary colors should be used sparingly to supplement the primary colors or draw attention to specific areas of content.

Color Usage Guidelines

All CMYK colors are used for offset printing, while all HTML/RGB colors are used for web, video, mobile, and desktop printing. It is crucial to use colors correctly to provide high contrast for Section 508 accessibility compliance. Gradient colors may be used as background colors and to create graphic elements, illustrations, etc.

The DHS Color Palette Picker Wheel is a vital tool for designers working on projects related to the Department of Homeland Security. By understanding the requirements and guidelines outlined above, designers can ensure that their creations are both visually appealing and accessible. Remember, the consistent use of the DHS color palette helps maintain uniformity and strong brand recognition across all DHS components – variation from these colors is strictly prohibited.
