Cant change colour in the text in Rich Editor in a Child theme… please help

Hi,

I have inherited a site which is using a child theme based on Thematic (a well known parent theme base).

basically my clients (the people how input most information) are unable to change the colour of any text when using they are adding pages/posts in the Rich Editor… Don’t mistake me, the button/color selector to change the colour is there, they select a color but when they update the page it simply reverts back to black.

I have tried overwriting the parent code in the child theme with a few things with no success, and have found that even if I allocate a specific colour to all Header styles this doesn’t seem to translate across to the site either, below is my “override” to the parent theme Typography.css I have so far:

/* All the @import lines have been moved to functions.php for better performance 

@import url('../thematic/library/styles/reset.css');
@import url('../thematic/library/styles/typography.css');
@import url('../thematic/library/layouts/2c-r-fixed.css');
@import url('../thematic/library/styles/images.css');
@import url('default.css');
@import url('quoterotator.css');
@import url('fullwidth.css');
@import url('../thematic/library/styles/plugins.css');
*/

/* Hide errant MapPress form in emails */
div #mapp0 {display:none};

/* Overriding the body, input, textarea styles from the Parent Theme */
body, input, textarea {
    Color:none;
	font: 12px Helvetica, Arial,sans-serif;
    line-height:18px;
}

/* Overriding the header styles from the Parent Theme */
h1,h2,h3,h4,h5,h6 {
	font-weight:normal;
	clear:both;
	color:#C00;
}

What do i need to change to allow my client to add any colour to text when they want.

Please help!
Thanks
