Re: [platform-ui-dev] Accessibility concerns with the Toolbar.

Aside: Good accessibility requires icons to be distinguished by something other than color. Anyone who is colorblind can tell you how frustrating drop-down color pickers can be. A better solution would be to display the name of the color contrasted (color and intensity) against a rectangle of the color. Of course, this doesn't change the fact that you *do* want the colors to show as well.

Randy,

You have a valid point. Please enter a PR for this in bugzilla and let us
know so those who want to add comments can do so on the PR.

Thanks

ActionContributionItem is converting Toolbar Icons to B&W by default.  I
think this makes it hard to distinguish between some Icons where color is
important.  For example, I might have a Drop-down color toolbar item that
displays the last color that was selected as its Image.  Converting this to
B&W defeats that.
Also, I think that B&W is not the Platform look and feel.  Sure, Internet
Explorer 5.0 did this, but version 6.0 has returned to color.  I don't
think Office ever made the leap to B&W.

P.S. ActionContributionItem$ImageCache never releases its B&W Images, thus
leaking resources.  In the above color example, the action would constantly
change its ImageDescriptor, causing a new B&W version of the current color
to get created over and over.  Even for static Actions, the color Images
are freed once the ToolbarItem is disposed, but the black&white Images
remain in the cache.
