NBT armor stand changing color must remove name

Put the summary of the bug you're having here

What I expected to happen was...:
The armor stand would keep it's name but change it's name's color

What actually happened was...:
I have to remove the name by putting \"text\":\"\" or it says An unexpected error occurred trying to execute that command and on hover Loading entity NBT

Steps to Reproduce:
1. /data merge entity thearmorstandidoraselector {CustomName:"{\"color\":\"aqua\"}"}

Essentially we can't change the color of an entity's name without overwriting it's name.
