I'm not sure why it was thought that the Arduino look (colors, etc) were an improvement on the mbed site. I actually think the old look and feel was easier on the eyes with regards to contrast and depth. The light orange is harder to read as text with a white background. Also, as a user I found that having a link in the top menu to the cookbook section was beneficial.

Just my opinion, thought I would share... and just for the record, I'm not usually afraid of change.

Am I alone here?

Not at all. Orange on a white background is not the most readable choice. If you happen to use chrome as your browser then I can help:

Create a directory somewhere. save the following as mbed.css

/* link colours, fairly standard blueish */
a:link {color:#0267C1;}
a:visited {color:#178FFB;}

/* background color for main content, I like a very light grey rather than white */
div.main-content { background:#eeeeee; }

/* each of the columns on the front page */
div.panel { background:#f2f2f2; }

/* each entry on the front page */
div.feeditem { border-width:1px
               border-style:solid;
		       border-color:#000000;
			}

/* forum rows, two colours for alternating entries */
table.styledtable tbody { background:#ffeeee; }
table.styledtable tbody tr:nth-child(even) { background:#eeffee; }

save the following as manifest.json:

{
  "manifest_version": 2,
  "name": "mbedStyleFix",
  "version": "0.1",
  "description": "Tweek mbed.org styles",
  "content_scripts": [
    {
      "matches": ["http://developer.mbed.org/*","https://developer.mbed.org/*"],
      "exclude_matches": ["http://developer.mbed.org/compiler/*","https://developer.mbed.org/compiler/*"],
      "css": ["mbed.css"]
    }
  ]
}

In chrome click on the menu button->more tools->extensions

At the top tick the developer mode option. Click "load unpacked extension" Point it to the directory you created the files in.

If any of these options are missing there may be an "enable developer mode" option you need to hit, I can't remember for sure.

That should now fix the worst of the problems with the new look.

Obviously you can change the colours and other style effect to suit your preferences, I may know how to inject style sheets, that doesn't mean I have any taste. ;-)

For changes to take effect you first need to go to the chrome extensions page and click reload on the extension and then reload the web page.

Here's the code above (with a few small changes) as a chrome extension:
