Description
Chart Colors has several predefined chart color schemes that you can quickly apply.
Share your color schemes in comments here. I'll will update indicator with shared color schemes.
To do this:
1. Go to Automate
2. Create instance for this indicator
3. Click Print Colors to Log button
4. Copy text from Log tab and paste as a comment here
