Characteristic value in label id

Dear hikashop,

I made some characteristics and selected them for my product.
On the product details page you see the characteristics summed up as radio's underneath each other.
They all show the value as text inside the label (See screenshot).

How can i put this text value inside the label id or class?
This way i can use css to hide the text and show a background color for example which represents the color of a product in this case.

I checked the file "characterics" inside the "types" folder but i only see the table getting build up there. But not the building proccess of the labels.

Code example

Current situation :

<label class="radio" id="hikashop_product_characteristic_18-lbl" for="hikashop_product_characteristic_18">	<input type="radio" onclick="return hikashopUpdateVariant(this);" size="1" class="inputbox" checked="checked" value="8" id="hikashop_product_characteristic_18" name="hikashop_product_characteristic[1]">	Wit	</label>

<label class="radio" id="hikashop_product_characteristic_18-lbl Wit" for="hikashop_product_characteristic_18">	<input type="radio" onclick="return hikashopUpdateVariant(this);" size="1" class="inputbox" checked="checked" value="8" id="hikashop_product_characteristic_18" name="hikashop_product_characteristic[1]">	Wit	</label>

Thank you
