What is Firebrick?
Firebrick is one of the named colors defined by the CSS Color specifications (keyword “firebrick”), so every modern browser understands it without a hex code.
Its hue angle of 0° places it in the red part of the color wheel, with 68% saturation (rich) and 42% lightness (medium-dark). It is a warm color.
Compared with the other red colors in the Aqeeb Studio library, it is lighter than 46% of them and more saturated than 19% of them.
Its relative luminance is 0.107, which makes it a dark color. That is below the 0.179 crossover point at which black and white text have equal contrast, so white text has the advantage.

Colors that go with Firebrick
Complementary color
Complementary colors sit directly opposite each other on the color wheel (180° apart). They give the strongest hue contrast, which suits calls to action and accents.
Analogous colors
Analogous colors are neighbors on the wheel, 30° either side of the base hue. They blend smoothly and are easy to combine in backgrounds, gradients and illustrations.
Triadic colors
A triadic scheme uses three hues spaced 120° apart. It is lively yet balanced, and works best when one color leads and the other two act as accents.
Split-complementary colors
Split-complementary keeps the base color and uses the two colors on either side of its complement (150° and 210°). The contrast is strong but gentler than a direct complement.
Tetradic colors
A tetradic (rectangle) scheme combines two complementary pairs at 0°, 60°, 180° and 240°. It offers variety but needs one dominant color to stay balanced.
Monochromatic variants
Monochromatic variants keep the same hue and saturation and only change lightness, which makes them dependable for UI scales and subtle layered designs.
