Change background form color

Try this:

.wpcf7-form {
background-color: rgba(61,128,191,0.1)!important;
padding: 10px;
border:1px solid #5178a7;
border-radius:7px;
}

Hi Zmokin,

Thanks for the help. I tried another way, by changing manually the main.min.css file.
I could change background and all fields colors.
