Get color general solution:
- Install http://eye-dropper.kepi.cz/ (Chrome extension color picker)
- Use UI.Vision to automate this Chrome extension (automate click on extension icon and then move mouse cursor to the x/y of where your arrow is). Then extract the color code with
storetext | id=color-toolbox-text
Get number from span title
- This is certainly possible. Did you try store Text yet? If you can post a link to the website I can give it a try.
