Please check out (i'll be glad to show you) this macro from GDG - I've paid $ annually for years to have access to this MASSIVE time saving macro.
It quickly identifies colors across all pallets for solid fills, gradient fills, and outlines.
Click on the color and every element of that color is selected, allowing you to recolor with one click or nudge the elements aside.
FAST way to change colors from CMYK to Pantone (for example).
Unfortunately GDG is no longer updating the macro, and it does not function in the latest releases of Corel.
Please develop your own version.
