If you like to color and you'd like to do so in a really easy and intuitive way, Paint By Number is a really fun app where you'll find a really wide selection of black and white images that are ready to be brought to life.
Coloring each drawing is really easy because you just have to pick one of the images and image the colors that should be applied. Then, simply click on each color and an area of the image will be highlighted in gray, this means you can apply that specific color there.
During the coloring process, you'll find more than 20 different colors that you can use to complete each level. On the other hand, you can choose a full view of the images or use a wildcard, which can make your task a lot easier.
Paint By Number is a pretty simple game that you can use to relax while you color the different images included in the gallery. You also don't have to worry about coloring outside the lines, because that's practically impossible!
