The possible colour hues you can mix with a three colour mix of yellow, magenta and blue are endless. Here are just a few of the possibilities using the De Atramentis Document Inks - Document Yellow, Document Blue and Document Magenta. The ratios shown are approximate - yellow:magenta:blue based on the number of drops of each colour used. A drop varies in size but it gives an idea. These mixes follow on from the two colour mixes shown in a previous post. These are painted into a Stillman & Birn Alpha A4 sketchbook with a brush at full strength.
Here are the same inks with approximate ratios of the three colours Yellow:Magenta:Blue
The second set of mixes is more random so no ratios are given. Only the Document Blue, Document Yellow and Document Magenta inks have been used.
