MtpIntros on "Simple question to change font color in footer widget"

Change the

#containerfooter {
color: #F7FE2E;
}

This:
#F7FE2E
Is the color of your footer text.
If you want your footer text to be white for example you have to change the css to:

/*
Theme Name:     Child theme Virtue
Theme URI:      http://www.wphulp.nl/
Description:    Child Theme voor Virtue
Author:         Bas
Author URI:     http://www.wphulp.nl
Template:       virtue
Version:        1.0
*/
#containerfooter {
    color: #FFFFFF;
}
