Home Forums Networks & Cross-Platform Networking Cable signal seems impaired

I have been working with colleagues in other parts of the country to create a website. Because the site is largely aimed at seniors, the background is white to facilitate reading text.

Everyone is seeing the site correctly, with the white background, except me. My background is a pale coral colour. However, the header, which has a white background, shows up as a white component in the pale coral background.

I have checked my monitor with various settings but I never get to white - just subtle variations on the coral. Also, I have visited a number of other sites with white backgrounds and they all render correctly.

I thought I should call the cable ISP and quack at them but, if other white backgrounds can be seen properly. maybe it's not the ISP's fault.

And no, I am not wearing my rose-coloured glasses.

Any thoughts?
