Placeholder styles for all browsers. Note the opacity resets, as this is how the default placeholder styles are applied.

placeholders.css

::-webkit-input-placeholder { /* WebKit browsers */
	color: #F00;
	opacity: 1;
}
:-moz-placeholder { /* Mozilla Firefox 4 to 18 */
	color: #F00;
	opacity: 1;
}
::-moz-placeholder { /* Mozilla Firefox 19+ */
	color: #F00;
	opacity: 1;
}
:-ms-input-placeholder { /* Internet Explorer 10+ */
	color: #F00;
	opacity: 1;
}
/* and HTML4 ones for old IE (you will need a polyfill for this) */
.placeholder { color: #F00; }
