Metal (Java Look and Feel)
メタル（Java ルック＆フィール） / 1998– / Style / Platform Screen Languages
Sun's default look and feel for Swing, built so that a program looks the same on every operating system. Metal was Sun's internal project name for it and stuck as the public one. Blue violet fills, thin straight borders, and a flat refusal to imitate the host platform are its signature.
Internal window title bars laid as a deep blue violet band over a pale blue violet field / A fine texture of dots and diagonal ticks stamped into title bars and dividers / Rectangular buttons with no corner radius, ringed by a one pixel deep blue violet line / The host system draws the outer window frame while everything inside it follows a different visual language

- Best used for
- Flattening the differences between operating systems so an internally distributed desktop tool reads as one picture everywhere · Recreating the screen of a turn of the century business application for a document or an exhibit
- Type
- Run a single sans throughout and separate levels with weight and color only. Keep to two type sizes and leave headings undecorated.
- Composition
- Fix four bands inside the window: menu, tool strip, work area, status strip. Leave the host window frame alone and paint only what is inside it.
- Material
- Combine three steps of blue violet, a pale field, a deep band, a darker border, with three steps of gray. Draw every boundary as a one pixel line and never blur it.
- Caution
- Since Java SE 5 the default theme has been Ocean, which drains most of the blue violet away, so building on the assumption that Metal means blue violet will not match what actually runs.
