Image Processor and sRGB Color Conversion

[chris.ram]

Hi,  I'm having an issue with Color consistency. My client requires a specific color background for her e-com images. When I took over from the other photographer, I was given (#ebe9e5; R235, G233, B229). 

I am working in Adobe RGB in Photoshop, 8 Bit and use Script>Image processer to Bulk Process images. 

Conver to sRGB is always checked, as well as include ICC profile. I understand image compression and that changing to sRGB will change my color space, and therefore my number above will no longer be the same, but why isn't it consistent? 

Shouldnt my background fill color be the same for every image if nothing affects it???

Sometimes my images will look consistent, and other times, 1 number will be off and my background color looks more pink or green. I've also tried sampling that color background after the conversion, but it still gives me incorrect color consistency.

Could you specify which software is used to view the resulting images? Additionally, have you attempted to record the steps involved in the action for profile conversion?

Hi Bojan, I am using a Web Browser and both Photoshop to view these images. There is a subtle, but obvious difference in the background despite, both images having gone through the process.

 I've never tried to record an action for the conversion, but that's a good idea. It just adds an extra step to my process, which is fine.

Jpeg compression will very often do this. The color component is more aggressively compressed than the luminance component.

One or two numbers off in one or two channels is normal. If you need absolute numbers, don't use jpeg.

Interesting @D Fosse What would you recommend for E-com deliverables to client? PNG?

If I needed absolute numbers, then yes, I'd use PNG.
