Change of background color drop-down menu form

Hello, thank you, I have a drop-down form, and they helped me before placing it so that the background is a color, which was in Tour Name * what I did was duplicate it and it does not stay the same as I do so that it has the same color characteristics of background like CSS that I have, what should I adjust?

select#avia_1_1{
background:#46653f!important;
}
