bluastre

Bluastre is a coined term used in color theory and graphic design to describe a hue in the blue–azure range. It characterizes a cool, saturated blue with a hint of greenish azure, positioned between blue and azure on the color wheel. The term has no official status in standard color systems.

Etymology: The name blends blue and azure to reflect its placement on the spectrum. It is often used to signal a specific target shade in palettes and style guides.

Characteristics: In digital color spaces, bluastre typically corresponds to hues around 210–230 degrees, high saturation, and moderate lightness. On the sRGB color space, it can be represented by values near #1E6EB8 to #2D78C0, though exact rendering depends on device and gamma. The shade tends to read as a deep, oceanic blue with a cool undertone.

Applications: Bluastre is used in branding and UI design to convey dependability, calm, and technical precision. It pairs well with neutrals such as gray, white, and charcoal, and adapts to both light and dark themes.

History and usage: The term gained popularity in design discussions and online palettes in the 2010s and 2020s as a practical descriptor for a distinct blue-azure shade. It is not a formal color name in CSS or other standards, and its specific rendering may vary across tools.
