Anomaly

After a re read of RoW I kept noticing more mention of color and it’s effect on the spen or magic system on roshar. There was the talk about Spren and the colors of gemstones which was interesting but the stranger one was about the pursuer and his husk. I noticed how it was mentioned that the color was drained from the husk leaving it dull and grey. is there a connection or similarity to nalthis magic? To me it read like the color was drained from his body and was needed for his next. just a thought. Thanks for any input!

I have a couple thoughts/ questions about the magic system on scadrial. As Harmony has come into existence by combining preservation and ruin is he a new larger shard that has all of the original two shards intent and will or is he a vessel containing the two shards together but still separate and in opposition. Ok so that is sort of a strange question but my thought process is that if harmony is a “new” shard would he be able to create his own new magic system? Along those same lines would the original three magic systems in this system change or disappear as the original shards have changed into something else?
