Bitmap changes color after editing

[bogyo.g]

Hey folks!

I have an issue regarding colors.

One of my clients wants me to change license plates on cars (he owns a dealership). I change the plates, and after saving to bitmap (jpeg), the shades of the colors  drastically change.
I'm saving them without ICC profile, without color conversion but the problem remains.

Can someone tell me why?

Thank you!

Use sRGB colorspace and include the profile with the saved image.

Thank you!

Including the profile solved the problem!

What are Photoshop’s Edit > Color Settings? 

What is the images’s original Color Space? 

Please set the Status Bar to »Document Profile« and post meaningful screenshots of the original and the untagged result. 

In which application does the appearance differ from the original – in Photoshop or some other application? 

If that application is not color-managed it is naturally irrelevant as far as color appearance is concerned. 

[NB, colourmanagement net]

You must embed the colour profile as a matter of principle.

Whichcolour profile to choose for your work?

In circumstances where users down the line may not use colour management or for web use then sRGB is generally considered to be the de facto working colour space since it is most likely to give a reasonable result..

I hope this helps
