Changing the color of NSProgressIndicator?

Question

What is the best way to change the color of NSProgressIndicator, is there an easier way than just to subclass it and then draw the whole component by myself?

Basically what I want to do is to have a similar component but with the ability to change the color of the bar.

I tried to google this but all the questions were quite outdated and didn't really concern the 10.10 OS X version that I am working on. Also checked cocoa controls and did only find 1 component that was for outdated OS X version.

You can use Quartz filters (e.g. hue adjust) for this directly in Interface Builder. This works better than expected.

It's in the Effects Inspector. Under "Content Filters" you can add "Hue Adjust"
