It is located in the blue region of the color spectrum, which is associated with feelings of calmness, trust, and stability. Royal Blue derives its name from its historical association with royalty and noble families, often being used in heraldry, flags, and ceremonial garments. In color theory, Royal Blue is a primary color, meaning it cannot be created by mixing other colors. Its RGB values are R: 45, G: 64, B: 251, indicating a strong presence of blue light with relatively lower amounts of red and green. This color is widely used in various applications due to its visual appeal and symbolic meaning.

The color #2D40FB, also known as Royal Blue, presents some accessibility challenges, especially in web design. Its luminance value is relatively low, which means that using it as a background color with light text may not provide sufficient contrast for users with visual impairments. According to WCAG guidelines, the contrast ratio between text and background should be at least 4.5:1 for normal text and 3:1 for large text. Therefore, it's crucial to pair Royal Blue with a very light color, such as white or a pale yellow, to ensure readability. Conversely, using dark text on a Royal Blue background should be avoided. When using Royal Blue for interactive elements like buttons or links, consider adding visual cues like underlines or borders to enhance discoverability for users with color blindness.
