to be honest i'm a light skin type of guy so don't see any real use in the other two ones. They don't appeal to me. One thing i think that ips should take into consideration if they are making multiple skins in the AAA rating by using a contrast analyser . I know currently there are no skins or the default ones don't meet these standards and its sometimes difficult to do but for people who have problems identifying colours or colour blind people this is a great accessibility improvement. You can analyse colours using the "colour contrast analyser" tool which is free.
