In your extra.less template (or whichever one), you can use the .button--cta class to edit it. Note that you need to put !important after most CSS attributes since else they don't get overwritten.
Examples:

Before:

After:

Code used:

.button--cta {
    border-radius: 10px !important;
    background-color: #00ffff !important;
    color: black !important;
}
