The Palette window includes twelve inkwells in an area for blending new colors when editing 256-color or True Color images. Two funnels are located over the left and right wells.
Click in either funnel with the left or right mouse button to pour Color A or Color B into the inkwell below. Ten colors are blended using the contents of the outer inkwells.
Any color in the blending area must be dragged into an inkwell of the actual palette above before it can be used.
Colors can be selected directly from the blend area and can also be dragged into the inkwells above.
