About Feishu
Feishu, sold abroad as Lark, is ByteDance's work suite: messenger, Docs, Calendar, Meetings and Base in one window. The interface is a white page cut into panes by 1px grey lines, set in #1F2329 ink at office density.
The colour comes from the bird logo. Its three flat fills, blue #3370FF, teal #00D6B9 and navy #133C9A, set the palette, and a deeper #1456F0 marks every primary action. Everything else stays quiet so that rows, messages and documents carry the screen.
