It seems that there is an inconsistency between demo page and actual repo.
From my observations:
.btn-primary and .btn-success have default bootstrap colors in the repo. However, on the demo page, these colors are customized to match overall color scheme. I think that this was caused by upgrading Bootstrap from 3.3.2 to 3.3.6. Hover colors are set correctly.
