Redesign: change navbar color for greater contrast?

[Cleop]

Following @SimonLab's feedback and @nelsonic's color suggestions in: #264 (comment)

• Add shadow to the navbar to improve contrast against page background color.

For context it's worth mentioning that @harrygfox's designs already have two variations of the navbar depending on the banner color that exists per page. A light version and a dark version. As we're reviewing the dark version, one option would be to have the light version throughout the entire site. Here are the visuals:

White
This is the white nav next to a white cover background (ignore the blue links in the navbar, they show up when you screengrab on invision)

Which looks like this when put next to the pages with a grey cover image:

AND/ OR

@nelsonic 's darker (near-black) suggestion

So do we want one color variation for the navbar or two? And do we want light or dark for these? @iteles @markwilliamfirth @nelsonic @harrygfox @SimonLab

Probably more apt to opt for a dark theme such as #403f3f

@harrygfox would you be able to confirm which color your prefer given the feedback about the contrast of your existing design?

@Cleop I've checked all the colours for AAA standard and the black on white and white on black are the best in terms of contrast ratio.
This is how I hope the menus to work and look:

@markwilliamfirth - this issue is confused. The issue is not about the contrast of text on a background. The issue is about the colour of the dropdown menu background on top of the background of the homepage.
See the bit where contact ends and the page begins:

The designs that Harry outlined are already implemented so if that's what you want then this issue can already be closed. What remains a question is, are we happy that the menu doesn't contrast with the page it is resting on in the case of the homepage.

@Cleop Harry's designs actually have some drop shadow on the menu - is it possible to add that?
