Colors Again

Usually graphics/pics will display a bit darker on PC’s. But I have noticed that my sites when viewed on a PC the colors are much brighter. A brick red will be almost orange, olive green is lime and beige is almost white. Changing the brightness and contrast on the screen is not helping either. Even Web Safe colors are displaying brighter.

Is this a Vista thing or is it something else.

I also tried to tweak colors using http://www.colorcombos.com/ on my pc and then transfer the hex # to my Mac but obviously now the colors are way too dark on the Mac.

Generally speaking, Windows PCs use a different gamma setting than Macs. Macs gamma was determined by finding the closest white for the “look of paper” when viewed on a Mac. PCs were not concerned about this. Nowadays it’s a different game. The ppi also is slightly different with Windows being generally defaulted to 96ppi, and Macs being 72ppi. Again, these days the game is changing abit with more PCs in the graphics arena.

Not exactly unconcerned, but a different agenda was in force. I wrote
a technical briefing about gamma a while back, and you can read it
here:

(It was a particularly intense kind of fun researching and writing
that article. I even wrote a little app to calculate the brightness
percentage variations that different gamma settings would have on
different tonal levels of RGB colours. Then someone increased my
medication…)

The ppi also is slightly different with Windows being generally
defaulted to 96ppi, and Macs being 72ppi.

But remember, this difference effectively relates to the rendering of
text. It ain’t really all that simple, dammit!

Thanks Chuck and Keith, the strange thing is – what I’m seeing is the opposite of what we are used to. It’s almost like the gamma is at the other side of the spectrum. Things appear just abnormally bright

Well, I don’t see brighter at all. I do see LOTS more blue in the PC image.

It sounds to me as though the PC you’re using is incorrectly set up
in some way. If you have calibrated and then profiled your display on
the Mac, and going further made sure you used sRGB (yuk) for your
original images, and perhaps set the display gamma to 2.2 (my
personal feeling is yuk again, but hey) - then you are working to the
best possible standard you can.

The only time you should ever consider tailor content to suit one
maladjusted display is if that is the only place it will be shown -
for example in a presentation or a kiosk device.

You should have seen the long version… :wink:

If the monitor or comp was maladjusted somehow, wouldnt the entire
image be off? The photo of the cityscape looks close, it’s only the
logo and menu bar colors that are radically different. I wonder what’s
different between those images… in the past we saw some differences
in gamma of png images versus say jpgs. I’d also want to make sure
prefs are set to millions, just in case.

I’ve always used a little app called Gammatoggle: http://www.thankyouware.com/gammatoggle.html

Its a really quick way (command-shit-9) to roughly compare how a PC sees your web sites colours. You can flick through your screen calibrations.
