The color (or colour) mixer functions by using additive color mixing. All possible combinations are listed in the chart below. Tip: A quick reference to which colors make other colors can be seen on the colored Venn diagram that's printed on the color mixer icon in the menu. This is convenient if you are playing in fullscreen. If you mix a secondary color (for example cyan) and one of the colors that makes it up (blue) the Color Mixer will make the same secondary color (cyan).
