I don't think the color mismatches are a Safari issue, per se, but I did pour my heart into this blog post that make the front page of Digg: http://blogs.smugmug.com/onethumb/2007/02/14/this-is-your-mac-on-drugs/ It seems to me it'd take the pressure off the Safari team if OS X shipped in the config that Apple suggests its users switch to -- a gamma of 2.2. Tell me where I'm wrong. Thanks, Chris I’m a huge Mac user and fan who was at NeXT during the let’s do a gamma of 1.8 days, back when monitors were dimmer and CMYK was the thing.

An image can be tagged as being sRGB with the ColorSpace tag, or as being AdobeRGB with the InteroperablityIndex tag. This is how most digital cameras communicate the color space of their image. Web-site-adorenment images (ones that might need to match with flash) generally don't have these tags, so it seems that you could take a big step forward by recognizing these tags. It would require that colorsync have sRGB and AdobeRGB profiles on hand, but don't they already? The up side to this is that images straight from the camera now are processed properly. I don't see any downside with what you mentioned (Flash/CSS). It's not a complete resolution of the issue, but it's a huge win-win step. I hope you'll consider it.

Your explanation is absolutely correct. More, strangely, or not, I have the private key in Keychain ! I think the private key is created when renew the certificate. The problem in Safari is about download certificates. When I collect the certificate ! And this is a problem in some CA. I tried in some CA internation and d`ont work. The problem is the Safari not open the window -DOWNLOAD, and the content of the certificate (cert. and public key) it is inside of Safari -like this page, but above, mixed with this posts. If the process is functioned, run, the window -Download, open, download the certificate for desktop. This does not happen. The certificate it is inside of Safari, in the main window, mixed with the content of the page. If you or other will be interested I I can send a print secreen. My intention is that somebody tells this problem of Mr. HYATT and other developers for fix this problem, bug ? Why Safari d`ont download, transferred, the certificates for descktop ? Best regards Manuel Spiff:
