Why white looks grey?

HTML & CSS
1

Here in top where you see yellow phone numbers, text looks grey and not white. Try to change number color to white and it will look grey. Why is that? Is it because of the background?

Find this in your style sheet:


header.header .tagline, header.header .phone
{
    font-family: "OpenSansCondensedLight" !important;
    font-size: 15px;
    margin-right: 30px;
    opacity: 0.4;
    padding: 15px 0;
}

Delete/comment out the line where the opacity is set to 0.4:

header.header .tagline, header.header .phone
{
    font-family: "OpenSansCondensedLight" !important;
    font-size: 15px;
    margin-right: 30px;
    // opacity: 0.4;
    padding: 15px 0;
}
