The ability to change the color of the cursor to something other than black or white when using the "ginput" function is not available in MATLAB.
As a workaround, you can use the "WindowButtonMotionFcn" together with the "WindowButtonDownFcn" to replicate the functionality of the "ginput" function while adding the ability to change the color of the cursor.
Attached is an example MATLAB code that illustrates how to do this.
Another solution using the "WindowButtonMotionFcn" together with "WindowButtonDownFcn" can be found on MathWorks File Exchange.
