Yes, you can do this in MATLAB! You should read about manipulating images . The Help pages include lots of examples, so you should be able to start working by copying and changing those.

And keep in mind that once imported, the image is just an array of numeric data, so you can locate and change any color values that you want to.

Once you start writing your own code, and something does not work as expected, come back and write a question giving the specific problem that you encountered.
