I am a visually impaired user and have to use inverse colors. But often I need to switch between coustom colors and original document colors i.e. when I need to follow some graphics or named text colors.

Therefore it would be very helpfull to have a quick button within the toolbar
to select "change color" or a keyboard shortcut or both.

Thanks for a great tool so far.
