Just wondering if there could be a 'grey' skin background (similar to the white noise background) to the website. I find the White one too bright and the yellow one not so good for work. If not, no worries.
There's a chrome extensions that makes websites SFW in a similar way that the white theme works, maybe you could try running that on the Yellow theme and see how it looks?
No worries - thanks for that. Will look into the chrome version.
