Some of you may have already heard of grayscale coloring and may not know exactly what it or is, or maybe this is the first time you are hearing about it. It’s a very recent trend in the adult coloring book world and it’s catching on fast. Grayscale coloring is a nice way to bring full scale images to life using your own choice of color. It is not line art like most coloring books but rather it includes all values from black to white and all the shades in between. You have a lot more freedom over what you use to color grayscale coloring books because of the amazing artistic freedom they give you due to having no solid lines to fill. Usually people will use fine markers or colored pencils for their coloring books and that’s it. With grayscale you can literally use anything you like and still get fantasic results!
