cange hover color button

Hello,

I’d like to change the color of the button on hover
I’ve already changed the color but I couldn’t change the hover which is set such as blue on the default theme.
Can you help me? please!?

here the code:

button, .button, input[type="reset"], input[type="submit"], input[type="button"] {
    background: #ff6e40;
    border: 1px solid transparent;
    border-radius: 4px;
    box-shadow: none;
    color: #fff;
    display: inline-block;
    font-size: 14px;
    font-weight: 400;
    letter-spacing: 1px;
    line-height: 40px;
    outline: medium none;
    padding: 0 20px;
    text-shadow: none;
    text-transform: uppercase;

}
