General Information about #023D99 (Smalt)

The hexadecimal color code #023D99, commonly referred to as Smalt, represents a very dark shade of blue. It is composed of 0.78% red, 23.92% green, and 60% blue. In the RGB (Red, Green, Blue) color model, it corresponds to the values R:2, G:61, B:153. In the CMYK (Cyan, Magenta, Yellow, Key/Black) color model, the approximate values are C:99, M:60, Y:0, K:40. Smalt derives its name from a historical pigment made by grinding cobalt glass, often used in paints and ceramics. This color exudes a sense of depth and sophistication, although its darkness limits its usability in certain design contexts where contrast is crucial.

The color #023D99, also known as Smalt, presents significant accessibility challenges, especially when used for text or interactive elements. Its very low lightness value (approximately 3%) results in extremely poor contrast against a standard white background. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is required for normal text and 3:1 for large text to ensure readability for users with visual impairments. This dark blue shade falls far short of these recommendations. To improve accessibility, it is crucial to pair #023D99 with significantly lighter colors, aiming for a contrast ratio that meets or exceeds WCAG standards. Careful consideration should be given to font sizes and weights, as larger text may be more legible, but this doesn't eliminate the need for sufficient contrast. Providing alternative color schemes is advisable to accommodate users with different visual preferences and needs.
