Last night, I mixed several Lanaset dyes (acid dyes) and made color swatches on watercolor paper. I was looking for greenery - the color of the year 2017 - but I also wanted to see all the different ways I could mix greens. I made 27 color swatches before I stumbled on what I thought would pass as greenery.
Basic color theory: green can be made by mixing yellow and blue. The Lanaset dye set has a restrained yellow, i.e., Yellow 2R, and a brilliant yellow, i.e., Yellow 4GN. These yellows will produce different greens when mixed with blue. The dye set also has two different blues. So, there are already at least four ways that yellow could be mixed with blue in the Lanaset dye set. In addition, by controlling the ratio of yellow to blue, a variety of greens, from bright to dark, can be obtained. Nice "olives" can also be obtained by mixing yellow and black. The Lanaset dye set also has a green, i.e., Green B (B means that the Green has a blue base). By mixing Green B with yellow, it is possible to obtain other shades of green, including olives. It is possible to mix each of Navy R and Grey G with yellow to obtain more shades of green, but I chose not to bother with Navy R in yesterday's experiment.
