In this tutorial, we learn how to enhance the color of your lips and eyes with GIMP. To change the eyes, use the ellipse tool to highlight each individual eye, then change the contrast of the eye as well as the color and highlights. Do this for both eyes, then save. To change the lips, use the lasso tool to highlight the outside and inside of the lips, then go to "select", "from path", and then change the color balance as you did on the eyes. Change it until it's the desired color you want, then change the contrast if you prefer. When finished, save your photo and you're done!
