Borderless Ads

Do these conform to recent policy updates?

Jenstar noted in her summary that ad colors must be such that all ad elements are visible (such as text and URL).

Does anyone know if this means borders must be visible?

Don't think there is a problem. Writing to AdSense support for clarification would be worth it.

From what I remember if you picked colours that meant certain aspects were not visible (eg white on white Ads by Google link) or something similar - the program automatically detected it and changed it to something visible.

Plenty of webmasters run borderless ads as it generally increases the CTR. It's up to individual preference though. As Adsense is a CPC program most webmasters want to increase their CTR. ;)
