Hi - I'm in a color mixing exchange over at ISGB. It has been lots of fun. We all choose a base color to mix other colors with. I choose lt. sky blue. It got a lot of grays with it (it gets that grey/black line around the ivory and yellow so this is why I got grays when I mixed with some colors). The very first color I mixed is my favorite. Here it is. It is with the base color and pea green:
I was really surprised with the mix below. Ink Blue is Periwinkle and amethyst mixed. I was expecting a purple color when I mixed the sky blue and the purple, but instead got this really nice blue color. The picture is not very good. Sorry.
I hope this is what you were looking for.
