Hi,
I want to translate one picture file from 3 colors mode (RGB) to 4 colors
mode (CMYB). But if i do that i've all marines blue turn in brown.

Also, remember that in order to display using the standard
viewwers in AVS, you have to end up in RGB or RGBA space. Thus,
even if you do your manipulations in CMYK, you have to get
back to RGBA.

RGB is based on colors which can be created/represented using a light source
such as a TV or your monitor.
CMYK is based on colors which can be created/represented using four color
process printing or ink on paper.
Some colors which can be created with the RGB method cannot be created with
CMYK and vice versa.
When you convert from RGB to CMYK, the Green and Red bits of your color seem
to be translating OK (resulting in brown).
However the Blue part of your color is 'out of gamut' and cannot be produced
using ink on paper.
Sounds like your software isn't doing a very good job of finding a close
match.
If the intention is to send the final artwork to print the only suggestion I
can make is to create an acceptable marine blue in CMYK mode. You won't get
an exact match for your RGB color but you may get close.
Also, you'll need to test print your CMYK color if you want the closest
possible match. Try as it may, your monitor can only produce an RGB
representation of a CMYK color. What you see may not be what you get.
