Hey guys ,
I want to convert a PSD CMYK image mode to RGB without losing the colors , also i want all the layers visible .
Thanks for your suggestions 
In PS open your file and go to Image - Mode - RGB Color (at the top menu), when window asking about merging layers will pop up, choose “Don’t merge”, PS will convert colors into rgb. Some tone loss is unescapable.
I already tried that but the colors were not matching hence I asked in the forum if there is any way by which the colors will be maintained , thanks though
