General Information about Ultramarine

It belongs to the blue color family and is characterized by its strong saturation and cool undertones. Ultramarine is often associated with the sea, sky, and spirituality, making it a popular choice for designs aiming to convey a sense of calmness, tranquility, or intellect.

Its versatility makes it a favorite among designers and artists alike.

The hex color #17118a, also known as Ultramarine, presents significant accessibility challenges, especially when used as a foreground color on a white or light background. Its low luminance contrast can make it difficult for users with visual impairments, including those with low vision or color blindness, to discern text or important visual elements. According to WCAG guidelines, a contrast ratio of at least 4.5:1 is recommended for normal text and 3:1 for large text. Ultramarine often falls short of these requirements, potentially excluding a segment of your audience. To enhance accessibility, consider pairing it with very light colors or using it sparingly for large graphical elements. Alternatively, use color contrast checking tools to identify suitable foreground and background color combinations that meet accessibility standards, ensuring a more inclusive design.
