Blue
General Information
#0000FF, commonly known as pure blue, is one of the three primary colors in the RGB color model. It represents the maximum intensity of blue light. In the additive color system, used for displays and screens, pure blue is created by emitting only blue light, with no contribution from red or green. It has a wavelength of approximately 450-495 nanometers. In subtractive color systems like CMYK, blue is produced by combining cyan and magenta pigments. This vibrant color is often associated with feelings of calmness, trust, and stability. Its digital representation, #0000FF, ensures consistent reproduction across various devices and platforms. Because it is an intense color, its usability in designs should be carefully considered, and it is often paired with softer, neutral tones to enhance its visual appeal while reducing potential eye strain.
The hex color #0000ff, also known as pure blue, presents some accessibility challenges, particularly concerning contrast. When used as a background color, it requires careful consideration of the foreground text color. White text on a #0000ff background can be legible, but readability should be tested across various screen sizes and for users with visual impairments. Darker text colors are generally not recommended due to insufficient contrast. In user interface design, avoid using #0000ff as the sole indicator for interactive elements, as colorblind users may not perceive it. Supplement color cues with text labels or icons to ensure inclusivity. When using blue for data visualization, provide alternative visual cues like patterns or labels, as a significant portion of the population experiences some form of color vision deficiency that affects blue perception. Proper contrast ratios, adhering to WCAG guidelines, are essential for ensuring web accessibility when employing this vibrant color.
