I give an elemet (object,text,..)an RGB color and when I want to apply an effect like shadow or opacity to another element(seperate) it changes the other RGB colors to CMYK .

Check your Transparency Blend Space

that didn't help, i don't know if you understand me well.😕

Hard to know what's going on with very little information and no screenshots/test files.

ok, sothe first image shows that when i apply an effect to the text it effect the all RGB color in my proj(document), the second image is before applying an effect to the text(the background color is a RGBvalue) .

To transfer an effect you should create an object style (with the important parameters) and apply to the other object. Have you tried this way?

Hi @Ibrahim29985365wk0y , It‘s possible you were mislead by Eugene’s link if you did not read the entire thread—the marked correct answer was not directly about the Transparency Blend Space.

CheckEdit>Transparency Blend Space. If your’s is set to CMYK, any transparent object on the spread will force a CMYK preview of RGB colors:

This document’s Transparency Blend Space is set to Document CMYK, so when I add a Drop Shadow to any page item on the spread, the spread’s RGB colors are previewed in the document’s assigned CMYK space:

If I set the blend space to RGB, the spread’s preview is in the document’s assigned RGB space (See Edit>Assign Profiles)

If the above does not help post some screen captures.

I was hoping the entire thread would be read.

You need to first ask yourself, what is the ultimate goal with this document? If you are going to print it, you need to know it's not the best to be building your document in RGB colours that are wildly out of gamut (i.e. out of the printer's ability to reproduce.). If you DO use RGB colours, it's good to know what your colours will look like based on your potential output device, say a CMYK printer. This is actually a good thing so you can predict what will happen in print.

As mentioned, the Transparency Blend Space will determine how your effects are rendered. If it's set to CMYK, all your objects on the page will be converted to CMYK based on your CMYK output profile in your Color settings.

Even if you leave Transparency Blend space set as RGB, if you have Proof Colors turned on (under View), your colours will change according to what your Proof Setup is set, typically a CMYK output profile. Again, this is a good thing and necessary proofing step.

If you are intending to export your document in only RGB colours for, say, screen use, you could chnage your Proof Setup to, say, sRGB, so even if Proof Colours is turned on, it should show you your intended appearance in RGB.

thanks sir🫡, appearently i wasn't aware of that 👍

No worries. Color Management of different Color spaces is a big one to wrap one's head around! Even professionals can get caught up by it. Good luck!
