I tend to design projects around the dominant hues found in the bitmaps used in that particular project.
Put down that Twinkie and pay attention! I once charged huge sums for this info. CorelDRAW might still have a bit of a bad reputation due to some of the early users who felt compelled to have every hue in the default palette – in each design! Buck that eyeball-jabbing trend by staying classy – work with a limited range of hues instead.
In X5 or later, create a new blank palette in advance. Drag & drop a bitmap to that palette. A dialog shows.
