The hex color #210BDB, a dark blue, presents significant accessibility challenges, especially for users with visual impairments. Its low luminance value of 8 makes it difficult to distinguish from black or other dark shades. When used as text, it requires a very light background to provide sufficient contrast, ideally achieving a contrast ratio exceeding the WCAG (Web Content Accessibility Guidelines) minimum of 4.5:1 for normal text and 3:1 for large text. In user interface design, avoid using this color for essential interactive elements like buttons or links without a very clear visual indicator and sufficient contrast. Consider providing alternative color schemes for users with different visual needs to ensure inclusivity and usability. It is advisable to use tools to measure contrast ratios and test with users to ensure readability and accessibility standards are met.

Web Design
In web design, this dark blue can be used for header backgrounds or call-to-action buttons to convey a sense of sophistication and trustworthiness. However, due to its dark nature, ensure the text on top is white or a very light color to maintain readability and meet accessibility standards. For instance, it can be paired with a clean, minimalist layout featuring ample white space to create a professional and modern look. It can also be employed in website footers or sidebars to create visual hierarchy and guide the user's eye through the content, but always ensuring to test it with different screen sizes and devices.
Fashion
In fashion, this deep blue can be used for evening wear or formal attire to evoke feelings of elegance and mystery. It pairs well with silver or gold accessories for a luxurious effect. It can also be used as an accent color in casual wear, such as in striped shirts or denim jackets. For example, a navy blue dress paired with gold jewelry can create a stunning and sophisticated look for a special event. However, when used in clothing, attention should be given to the fabric and texture, as this color can appear different depending on the material.
Interior Design
In interior design, #210BDB can be used as an accent color in a room to add depth and richness. It can be paired with lighter colors, such as cream or gray, to create a balanced and inviting space. It could be used for accent walls, upholstery, or decorative pillows. For instance, a living room with gray walls and navy blue accents can create a cozy and sophisticated atmosphere. However, it should be used sparingly, as too much dark blue can make a room feel small and claustrophobic. Proper lighting is crucial to bring out the beauty of this color in interior settings.
