The new icon is confusing and not at all Mac like.
All common applications have a big, one block, icon. See Chrome, Firefox, Skype... you name it.
The new (15.0.2) IntelliJ icon has a small relevant "black" part in the center surrounded by coloured noise.
It was a shock to see it once updated to the new version.
Please follow common and working conventions, it's important. See for example: https://developer.apple.com/library/mac/documentation/UserExperience/Conceptual/OSXHIGuidelines/Designing.html
See how it appears in my dock. There is a continuum of icon convention except for IntelliJ.
Thanks in advance
