Can i paint over a ceramic piece? How?

I have a ceremic wall panting that my now deceased mother made for me 15 years ago. My kitchen has been remodeled and I would love to hang the matching folk & spoon pieces but it has orange in it and my kitchen has apples. I would love to repaint the oranges to red. It was originally baked in a kiln and I am afraid I will ruin it. Has anyone done this? How? Serious replies only, please. Sincere thanks!
