Blue Gem
General Information about #210F8C
The hexadecimal color code #210F8C represents a dark shade of blue, often referred to as 'Blue Gem'. It is composed of 12.9% red, 5.9% green, and 54.9% blue. In the RGB color model, it's equivalent to (33, 15, 140). Its HSL values are 249 degrees hue, 81% saturation, and 30% lightness. This color leans heavily towards the blue spectrum, resulting in a deep, rich tone. The color is more appropriate for backgrounds, and should be carefully combined with colors that have high contrast, such as white, yellow, or a light shade of green, so that it can be more accessible. Colors with similar attributes can be found in the same part of the spectrum.
The color #210F8C, also known as Blue Gem, presents significant accessibility challenges, particularly for users with visual impairments. Its low luminance value of approximately 3% means that text rendered in this color will have very poor contrast against a white background, falling far short of WCAG (Web Content Accessibility Guidelines) recommendations for contrast ratios. A contrast ratio of at least 4.5:1 is generally required for normal text and 3:1 for large text. Consequently, using #210F8C for text can make it nearly illegible for many users. To improve accessibility, pair Blue Gem with much lighter colors like white, yellow, or very light shades of grey, ensuring sufficient contrast. Furthermore, avoid using it as the sole means of conveying information, such as in links or error messages, without additional cues like underlines or icons.
