Fantasy and Fairies - A GRAYSCALE Coloring Book features the fairies, dragons, mermaids and more This is a GRAYSCALE coloring book. Some of the pages are a bit darker than others. 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. Some find this type of coloring intimidating but I assure you, once you find the right medium to use, you will really enjoy it. The key to this type of coloring is to use transparent colors mostly - that way the shading comes through. My favorite medium for grayscale coloring is alcohol markers such as Copic markers and others. Artist Loft (Michael's brand) markers work wonderfully as well. Pastel chalks and colored pencils work well with this type of coloring too. I suggest using colored pencils for coloring over dark areas (transparent markers won't work to cover dark grey or black). I would recommend not using crayons or anything too opaque (except for using over dark areas) because it will cover the shading. If you use markers, please put a piece of heavy paper between the pages to prevent bleed through. Also, this coloring book is not suitable for any wet media such as watercolor or watered down paint of any kind. You are free to copy the pages (for personal use ONLY) and print out on watercolor paper or heavier paper if you like so you can try different mediums.
