Yttrium is a dark style for XenForo 2 which inspired by Yttrium element. Yttrium is a chemical element with symbol Y and atomic number 39. It is a silvery-metallic transition metal chemically similar to thelanthanides and it has often been classified as a "rare earth element".
In 1787, Carl Axel Arrhenius found a new mineral near Ytterby in Sweden and named it ytterbite. Elemental yttrium was first isolated in 1828 by Friedrich Wöhler. And the flag of Sweden is dark blue.
By those inspirations above, we created Yttrium style with the dark blue as the main color. The navigation bar is adjusted to the dark state blue, similar to the dark blue. By doing this, the whole style is dark. So we choose white color for the color of text.
Moreover, Yttrium is the symbol of TV transmitters, so we hope that it will bring the best signal to your home.
