Parallax Slider Text Color

I assume its possible to change the text color in the parallax slider.

I’d like to change that text color.

I tried modifying /wp-content/themes/orizon/css/blue_css/parallax_slider.css to use color #fff (white) assuming this would be it but it does not appear to change.

.da-slide p{
	width: 45%;
	top: 115px;
	color: #fff;
	font-size: 16px;
	line-height: 26px;
	height: 80px;
	overflow: hidden;
	font-family: 'Economica', Arial, sans-serif;
	font-weight: 400;
	font-style: italic;
	z-index:99;
	text-shadow: 0px 2px 3px rgba(0, 0, 0, 1);
}

Can you verify this is the correct part of the css to modify, perhaps Im just having a caching issue?

Thanks
