To select an element by attribute value, you can use this syntax:

$('[attribName="value here"]')

Where attribName should be replaced with attribute name such as name, title, etc.

To add a new attribute value, you can use the attr method.

Example:

$('[attribName="value here"]').attr('attribute name', 'attribute value');

And this is how you can change the background color:

$('[attribName="value here"]').css('background-color', 'green');

Note you should replace dummy attribute names and values as per your requirements.
