Hi Ijeoma

Thank you for reaching out to us. 

You can change the font size and color using custom CSS code, but please note that the Search box will change together with the Show entries field.

Here is the code you can use for this

Show entries:

.dataTables_length {
font-size: 20px;
}

.wpdt-c.wdt-skin-material label{
    color: green !important;
    }

 Showing 1 to #:

.dataTables_info {
    font-size: 20px !important;
