font and background color problems

Ive selected a theme color. The font color is a dark green and the background for the field is white. The font is typing out WHITE so it appears WHITE ON WHITE.. so there is an issue with the theme that used to function properly. 

Ive now selected the background color to be a grey instead and the white font that is supposed to be a dark green now shows up EXCEPT in CHECK BOXES!!

There is a problem with the COLOR THEME! 

this happens with every color theme that I select

If you want the checkbox and radio buttons to be black when check/ticked, please try adding this code below to your form:

.form-checkbox-item:not(#foo) input:checked + label:after {

    background-color: #000000!important;

    box-shadow: 0 3px 0 0 #000000, 3px 3px 0 0 #000000, 6px 3px 0 0 #000000, 9px 3px 0 0 #000000, 8px 6px 0 0 #d5eef3, 10px 1px 0 0 #d5eef3;

}

.form-radio-item:not(#foo) input:checked + label:after {

    background: #000000!important;

}
