Re: pgweb commit: Logo updates for PostgreSQL sponsors

There's also at least one logo that doesn't look great in light mode:

It looks like someone grabbed a version of our logo with transparent bits
intended to sit on a dark background. Where can I send a more suitable logo?

In regard to the dark mode question, I ran across this Stack Exchange post
<https://graphicdesign.stackexchange.com/questions/162534/what-is-the-best-way-to-handle-dozens-of-partner-logos-in-dark-mode>
which suggests using CSS filters to invert logo colors and apply grayscale.
Here's what a filter: invert(30%) grayscale(80%) looks like:

The numbers need tweaking, but I think the approach is promising.

One catch is that some brands really don't like their logos futzed with.
E.g., the AWS trademark guidelines
<https://aws.amazon.com/trademark-guidelines/> state

*8. Logo Display. *AWS will supply logo images of the AWS Marks for your
permitted use. You will not alter the logo images in any manner, including
but not limited to changing the proportion, color, or font of the AWS
Marks, or adding or removing any elements to or from the images. AWS Marks
must appear by themselves, with reasonable spacing between each side of the
logo image and other visual, graphic or textual elements. Under no
circumstance should the AWS Marks be placed on any background which
interferes with the readability or display of the logo images. You will
comply with any relevant graphics standards provided by AWS.

It might be safer to just use a light background behind the logos (I think
an off-white like #efeeee is a little less jarring in dark mode than pure
white). A second dark-mode-specific logo is a good idea—I can probably help
with the CSS magic (to some extent) if I understand the implementation
better (e.g., if the logo img has a src attribute that includes in "-dark",
we could match that with a CSS selector).

Thanks,
Maciek
