Different colour shades?

 10:48 am on Jul 20, 2005 (gmt 0)

Hi all,

Just been saving images as optimized (photoshop)..

Saved a few images in different formats, the gif's and jpg's come out as expected the PNG24 format come out with a different shaded blue than the rest.

Does this happen alot with PNG or is it my colour profiles?

this hasn't happened to me before, are you using the same palletes?

It's probably just a palette issue, but do bear in mind that PNGs have an embedded gamma profile, and GIFs don't.

I'm not sure of all the practical consequences of this, but I do know that Safari on the Mac incorrectly colour-shifts PNGs, so they don't look the same as GIFs.

have you calibrated your monitor with your image editor?
are you using the 'save for web' method of optimization and not 'save as'? the rendering engine of the 'save as' method is not nearlt as robust as save for web.
be sure your files are in RGB mode and not CMYK. it could be the color profile,but the default setting is pretty decent. I would also recommend checking to make sure you've selected a web color palette. it is not loaded by default--you have to select it from the palette options if you are using photoshop.
cheers, kat

Pixelkat, I'm not sure it's possible to save a PNG or a Gif as a CMYK...

damn. I accidentally hit enter instead of the space on my ipaq keyboard...sorry about that. anyway, it is only today that I learned about the default gray thing at a developer blog. IE 7.0 is in limited beta distribution, so there's a lot of buzz over new added features, or rather, the lack thereof. MS did fix the png problem in v7.0, and is working on tabbed browsing, but to date, standards-compliancy is not even a blip on the priority radar--at least not yet. for now, we'll have to settle for gifs and jpgs. kat
