The hexadecimal color code #0306D3 represents a very dark shade of blue. In the RGB color model, it is composed of 1.18% red, 2.35% green, and 82.75% blue. This indicates that the color is overwhelmingly dominated by blue light. In the CMYK color model, the color is composed of 99% cyan, 97% magenta, 0% yellow, and 17% black. This means that almost all cyan and magenta inks are needed to produce the color. The low percentage of red and green in the RGB model and the high percentage of cyan and magenta in the CMYK model result in the characteristic deep blue hue. This color is often associated with stability, depth, and trust.

The color #0306D3, a very dark blue, presents significant accessibility challenges, especially when used as text against a white or light background. Its low luminance value results in very poor contrast, making it difficult for users with visual impairments to read. According to WCAG guidelines, sufficient contrast is crucial for readability. A contrast ratio of at least 4.5:1 is recommended for standard text and 3:1 for large text. This dark blue shade likely falls far short of these requirements. To improve accessibility, consider using #0306D3 sparingly for purely decorative elements or pairing it with much lighter colors that provide adequate contrast. Alternatively, using this color for interactive elements like buttons is not advisable unless the contrast is significantly improved. Ensure text using this color is also large enough to improve readability. Testing with accessibility tools is critical to ensure compliance and usability.
