Parent Theme button in Theme Directory looks weird on hover

[SergeyBiryukov]

See the combined screenshot of hovered buttons.

1. The first one seems fine.
2. The second one seems fine too, not sure why it has a different color though.
3. The third one appears to have too low contrast and doesn't look good to me.

Tested with Firefox 23, Chrome 29, Opera 15.

The current CSS is:

.col-3 p.preview-button {
	background-color: #4EAF21;
}
.col-3 p.preview-button a:hover {
	color: #ACFF90;
}
.col-3 p.parent-button {
	background-color: #4E21AF;
}
.col-3 p.parent-button a:hover {
	color: #AC90FF;
}

Fixed.

Recent CSS changes had affected the styling for those buttons, giving them all the reddish-orange color of the download button. The other two buttons were supposed to be green and blue, respectively (hence the differing hover colors, which were meant to relate to their unique background colors).
