I don't think the pseudopupils are a feature of the eye distinct from any other part, it's just what the individual facets look like viewed at a shallow angle.

edit: not that there aren't bugs with different colored regions of their eyes. I'm not sure about the functionality of those tho, is it for vision or camouflage or looking good for the ladies or what. Will google

That's because email and fax machines aren't businesses either. However commercially run email providers def go through this process.
