Hi, I'd like to create a program that can do things on condition that certain point on the screen is of a certain color. Do you think it's possible? If so, what is the best way of doing it?

Read all about it in the Robot.getPixelColor() method Java docs.
kind regards,

robot.getPixelColor() seems OK to get RGB of just one pixel, but when I try to scan the whole screen it gets extremely slow. I know there is such thing as GetPixel(hdc, x, y) in C++ which is WAY faster than java's robot.getPixelColor().
I've tryed to capture the screen into buffered image and scan that with a faster method image.getRGB() But it's still way slower than I would expect and much slower than C++'s GetPixel(hdc, x, y). Is there a faster way of doing this in Java?

Did you try to get the Raster using the BufferedImage.getData() method?
A Raster can give you a simple int array filled with pixel values.
