The style of the links in the post

In the text of the post links are not distinguished, they are the same color as the text. I believe that this is not quite right and would like to change the color of links in text only post. Prescribe the code, but nothing changes.

.entry a
{
color: #dc143c;
text-decoration: none;
}

.entry a:hover {
text-decoration: underline;
}

Please tell me how to change the color of links in text only post (everything else remains the same)? What and where you want to change? Thank you.
