Well - months has passed and yet no update. The Eyedropper tool will not pick the color using a wacom + a mac ... and when you do it using the trackpad it is still not the exact same color. I can not understand why this hasn't been fixed yet. The problem with picking the wrong color has been going on for years now - the wacom/mac problem has been going on for at least 6 months. Please ... put some serious effort into your product AND support.
This has been fixed in the latest release Animate CC 2015.2. Please update your copy of Flash/Animate CC to the latest(184.108.40.206) using your Creative Cloud Desktop application. Sign-out & Sign-in in case if you do not see Animate CC 2015.2 in your Creative Cloud app.
