When you use the drawing or text features in the Instagram app, you can see 27 colors available at the bottom of the screen. Here’s the cool part: You’re not limited to these 27 colors. Simply hold down any one of these available colors to choose from the whole color spectrum. Plus, if you can’t get the color you want, you can always use the color picker tool in the bottom-left of the screen. Just tap it and select a color from your image.
