The tattoo problem is for those with very thick dark tattoos, basically the lights flash and pick up changes in the blood flow which show the heart rate, when heavily tattoo'd there is several layers of ink between the watch sensors and the major blood vessels that it will record from, it is simple physics really, and, no dark pigmented skin is not the same as heavy tattoos as light will still penetrate dark pigment skin.
Russlush3 - from what i can see from the edges around your moto 360 of your tattoo, whilst dark purple it doesn't seem as thick (not as many layers of ink) so apple watch may still work just like your moto.
