Siahi is described as a "deep ocean blue." It's a muted, blue with a hint of green and a pearly sheen. It had semi-sheer pigmentation in a single stroke that was somewhat buildable to semi-opaque coverage, but it tended to look faded, even when built up. The version here is more muted, less shimmery/more blue-leaning than my prior version. It lasted for ten hours--this formula just doesn't budge on me.
