Changing CTA button colour from pink

I am trying to change the hover and button colour from the pink to #c8a2c8 - I have read related threads on the forum and I have added CSS code, but on my homepage some post titles are #c8a2c8 when not hovered. They should all be black and only #c8a2c8 when hovered (like the pink previously). Also, I can’t change the submit button colour in the sidebar widget? Any suggestions, gratefully recieved

Hi there,

Here is the CSS code to change the color you mentioned above:

.entry-meta .author a.url:hover, .entry-meta .posted-on a:hover {
    color: #c8a2c8;
}

input[type="submit"] {
    background: #c8a2c8;
    border-color: #c8a2c8;
}

input[type="submit"]:hover {
    border-color: #c8a2c8;
    color: #c8a2c8;
}

Add the code to Customize > additional CSS.

Regards,
