Lets say I have an object that already has a color on it and all I want to do is paint something small in the corner. I dont want to change the original color just add on top. How do I do that?

Right click on the texture in the paint tool; choose "Add layer"; then paint on that layer. On the pic below, I painted a green spot on top of the mauve cylinder.
Yes but what if I already have a color on the object, I dont want to change it I just want to add to it. Lets say that cylindar was already a rose color when you went into to paint and you just wanted to put a green dot on it. How do you do that?
Interesting - I originally started to post that you should just be able to paint right over it just like argus1000 said, but I tried it and it only works with a primitive. With a vertex object, clicking the 3DPaint tool clears out your original texture.
Weird.
With a vertex object I had to paint in 3D then edit the shader to mix the new painted texture with the original texture, which I had to reload (I used a multiply since I just painted in black on white).
Have you tried to export the texture as a PSD or PNG into Photoshop (or Gimp) and add a non-destructive layer there? Then you can import it back into Carrara. You can change that layer any time you want. Works for me.
There is usually more than one way to do something in Carrara. Here is another way to paint just part of a model that already has a texture map or other shader on it. Use the 3D paint tool to paint a black/white opacity mask to isolate the area that you want to paint (white where you want to paint, black where you don't). Use an unused channel if available and save to a separate file. Reload the prop and then paint what you want to paint. Reload the prop one more time. It should have the original shader. Create a complex shader/layer list in the top level of the shader tree. The original shader should slide to the first layer in the list. Create a new layer and choose multichannel. Insert you painted texture map in the color channel. Use the black/white painting for the opacity mask. The white area will be where the second painting shows up.
I used this method to paint blood on the front of the Freak's warhammer, which is the first prop in my Daz content folder. The specular channel was empty so I created a new texture map for it and painted the black/white opacity mask. Saved that separately. I then reloaded the hammer and again created a new map and painted the red blood. Saved that file separately. Loaded a fresh version of the hammer one more time. Used the layer list method to have the original prop texture and the blood.
