General Information about #21098F

The hex color #21098F, also known as Blue Gem, is a dark shade of blue located in the blue-violet region of the color spectrum. It is created by mixing a small amount of red, a very small amount of green, and a significant amount of blue. This color evokes feelings of depth, mystery, and sophistication. In color psychology, dark blues are often associated with trustworthiness, stability, and intelligence. It's a color that can be used to convey authority and professionalism, making it a popular choice for corporate branding and websites. The color is a tertiary color, created by mixing a primary color (blue) with a secondary color (a blend of red and blue that forms violet/purple), giving it a unique character compared to pure primary or secondary colors.

The hex color #21098F, also known as Blue Gem, presents some accessibility challenges, primarily due to its dark nature. When used as a background color, it requires very light text to ensure sufficient contrast for readability. A contrast ratio of at least 4.5:1 is recommended for normal-sized text, as per WCAG guidelines. For larger text (14pt bold or 18pt regular), a contrast ratio of 3:1 is acceptable. Using a color contrast checker is highly advisable to verify compliance. When using #21098F for text, it should be paired with a very light background. Consideration should also be given to users with visual impairments; providing alternative text or visual cues can enhance usability.
