Why do my colors look different when I use the “Save for web” option in Photoshop?
When I used the “Save for Web & Devices” option in Photoshop CS3, I noticed the colors of the saved image looked different from the colours of the original. After some web-surfing-research I found out the problem was this: by default, images saved with Save for Web and Devices are converted to the sRGB color profile. Switching this option off solved my problem. The option is hidden in the little arrow button right from the color preset selection menu (view screen-shot).
