Why does the same RGB value appear different between Interface Builder and Photoshop?

I have a UIImageView that I've pointed to a PNG who's background is RGB(240,240,240). I've then set the parent UIView's background to the same colour in Interface Builder.

You'll notice that they are slightly different. When I take a screenshot and re-examine, I see that the UIView's background in IB is not RGB(240,240,240), but RGB(236,236,236).

Why is this??

RGB value is meaningless without knowing the colorspace. Make sure you choose "Generic RGB" colorspace when selecting the color using the RGB sliders in Interface Builder.

I had to tweak the numbers I used in IB to get my colors to match.

For example: You want (240,240,240) and it gives you (236,236,236) dispite that you entered (240,240,240).

I entered (244,244,244) and it gave me a color closer to (240,240,240). I figured if I entered 240 and it gave me 236, then I should add 4 to my original colour code.

I had to do this a couple of times to get the right number.

Not an elegant solution but worked for me.

Do you have a manufacturer specific monitor driver installed? Have a look at the monitor profile. Its probably different from the colour profile in photoshop
