Minor color shift in jpegs and Photoshop CC/CS6

over 6 years ago from , Designer at Kraftwerk

Hi everyone,

i am using this here to find out if i messed up something in a big way or if something is wrong with my copies of photoshop.

I try to save a jpeg at 100%, optimized with one color. The color is #e20074. I set it in photoshop, i fill it, i save for web and the result is a color shift from #e20074 to #e30074. I know that this is a very minor shift, still i do not want this to happen. When i save it as a png the color shift does not happen. Is there any way to fix that? I did not convert it to sRGB, i did not add a profile or anything. If not, is there a plugin that can actually save images with the correct colors?

Link to the jpeg: http://cl.ly/image/152A09172w3Y/Untitled-1.jpg

Thank you for any help. Flo

    Thanks for the information. Is there any plugin that makes more sense to use/is the best? I am tending towards PNGHat so i can compress pngs a little and keep file size at a usefull level.

    The photoshop plugin from tinypng says: Worry-free color management Images are automatically converted to sRGB for maximum compatibility. Whether you use color profiles or not – it just works. I dont know if i want that cause all my files are untagged RGB or does this not modify the color space?

    JPEG compression does a conversion from RGB to YCC, and decompression does a conversion from YCC to RGB. There’s several ramifications, including rounding. You simply can’t expect identical results from JPEG.

    PNG8 can be a good compromise when you need to save space, but also maintain exact colours.

    This is a common longtime issue saving jpg images for web. They tend to lighten up so try adjusting the brightness and saturation level a little bit to compensate. It takes a little trial and error until you get the results you are looking for.
