Hi Evgenia,
To colour a link, make sure you have selected only it and not any of surrounding spaces or words. This will result in an html similar to this one:
<a href="http://www.jqwidgets.com/" style="color: rgb(255, 0, 0);">jQWidgets</a>
Otherwise, only the surrounding text will be coloured, as is the expected result of a code such as:
<span style="color: rgb(255, 0, 0);">link to <a href="http://www.jqwidgets.com/">jQWidgets</a>
</span>
