I have really weird problem with colors in interface builder. I set a color on one UI element, for example UIView, and then I want the same color on UIButton…but when I try to do so, colors are often different – I mean little bit different tone, not absolutely different color. How is this even possible ??? I've tried to use RGB sliders, and other sliders, also that color picker tool… Only thing that helps me sometimes is, when I create new UI element. Anybody had the same problem and knows what's going on ?

You may have a bad connection in your xib.
I've had this error many times. While TechZen's answer is absolutely right in this case, another common cause is when you change the name of a IBOutlet property in your .h/.m which you've already connected up to File's Owner in the nib.
From your nib:
- Select the object in IB and go to the 'Connections Inspector'.
Under 'Referencing Outlets' make sure that your object isn't still connected to the old property name... if it is, click the small 'x' to delete the reference and build again.
Another common cause if you are using Storyboard, your UIButton might have more then one assignings (Solution is almost the same as for nib):
- Open your storyboard and right click the UIButton
You will see that there is more than one assign/ref to this button. Remove one of the "Main..." greyed windows with the small "x":
- In the project navigator, select your project.
- Select your target.
- Select the "Build Phases" tab.
- Open "Link Binaries With Libraries" expander.
- Click the + button.
- Select your framework.
- (optional) Drag and drop the added framework to the "Frameworks" group.

Interface Builder filters colors through your monitor's current color space by default. You can change this in Xcode4 IB by bringing up a Colors dialog, clicking the Sliders tab, then clicking the little dropdown button under the magnifying glass that looks like a color spectrum. This will bring up a list of available color spaces -- select Generic RGB and adjust the sliders as necessary to get the correct color.
