As you see from the link, -

I have an image and two catagories

Pilasters and Doors

Is their a code where you click on pilaster or doors and the colour palatte appears for the user to click on to change on image

also if you see i can only select one or the other color catagory but not both, i like user to be able to select color of pilaster and doors and both appear on image together

can this happen with javascript

hope this make sense
