a client wants me to send a pic over iphone. I have a digital illustration in photoshop using different purples violets and pinks. When i save it to web(using RGB) and add it to my photos in my iphone4 there is a noticable difference in color, much duller. Am i doing anything wrong? or does the iphone not support such a variety of colors, i havent had a problem like this before but the colors are MUCH duller. Please help!
you are most likely saving your problem images in AdobeRGB or ProPhotoRGB colorspace
you probably just need to Photoshop Edit> Convert to Profile: sRGB BEFORE saving a copy for delivery
File> Save For Web & Devices CONVERTS to sRGB by default the last time I checked, you may want to check that option (keep the Convert to sRGB option checked)
