In this how-to video, you will learn how to make a rainbow in an image. First, open the program. Make a new layer and go to the gradient tool. Change the style to the one that looks like a rainbow. From here, change the sliders that you have the colors of the rainbow selected. Once this is done, slide the rest of the sliders near the last color, which should be red. Save the gradient and click okay. Now, go to the bottom left hand corner until a plus sign shows. Click and drag until you get the rainbow with the size you want. Now, click the layer and change the opacity to your liking. Click the move tool to move the rainbow to where you want it, and you are done.
