Change link color in posts

Hi, when I write a blog post and turn some words in the normal text into links they change from the normal text color grey to a slightly darker grey which you can barely recognize. It´s not underlined and nothing, so no one will really see that it´s a clickable link. I found a simple but not very desirable solution: Put the link on the word, then change the color of the word and underline it. Works but is not what I want. I want the color of the word to automatically change to blue (instead of just the mini change to the slightly darker grey) or whatever color I want when I put a link on it. It doesn´t neccessarily have to be underlined or change color while hovering and whatnot, people just have to see (through the different color) "Ah, this word has a different color. Seems to be a link". The sidebar links and blog headlines and other links etc. should remain untouched by this. Just the normal blog post text. Is there a simple solution to this? If not, I´ll keep doing it the way I described above which wouldn´t be dramatic. Theme is Simple Catch Pro. Thanks.
