Can't find color bar LO Writer V5

I want to alter the brightness of an imported image. From what I’ve read I think I need to use the Color Bar, but where is it?
Help tells me: “To access this command… Choose View - Toolbars - Color Bar.”
However, in Toolbars I can’t find anything labeled as Color Bar. Where might it be?

Select the Image toolbar, and it the Color icon.

Ah, eventually found it, thanks.
It’s under Toolbar>Customise>Toolbars Tab>Color. Not as listed in help (for me anyway).
