When Clara studied the Tides, she decided she was obviously an Indigo. Her decision was based solely on her liking indigo as a colour more than what it represented.
She liked to think she was calm and influential, an upstanding member of her community and moral and trustworthy.
The truth was more reflective of her as being silver. A lying self-serving woman who pretended one thing and acted another.
She always came across well to anyone who met her, and she was always willing to help you out whenever the need arose. But behind your back, she was happy to assassinate you.
She had this belief that it was for your good when she stepped in offer guidance of the sort you couldn’t for fear of retribution ignore.
She did have a concern about the legacy she might leave on the world which is why she tried so hard to combine the two colours, which as we know are not very compatible and in Clara’s case showed up like the proverbial dog’s balls.
