Anyone overcome issues getting cmyk colors to look the same as rgb colors?

Hi,

This is a first for me.  Thanks in advance for any input.

I'm working on a .psd file that was created cmyk.  I have the doc together but my problem is I am unable to replicate the colors I have in similar rgb document.  I've tried copying all of the layers over from the rgb file to the cmyk file but the color is still off -- way off.  Hot blue becomes dark purple.

This is for print (business card).

The rgb color is #0000ff.  I looked around and could not find a comparable color in the cmyk palette.  I tried some of the on line rbg-to-cmyk converters but to no avail.

Am I missing something or is there no way to resolve this?

Thanks in advance...

    you want to read up on Photoshop out of gamut colors, proof colors, softproofing...

    hot blues, purples, greens in RGB look awful when converted to CMYK because they don't translate well

    Hello, this is probably a shot in the dark since it's been 6 years, but I have the exact same issue, with the exact same colour (#0000ff in RGB), so I was wondering if you remember how you solved it? Thanks a lot !

        That is an out-of-gamut color ( will not print ).  CMYK = 91C, 72M; RGB = 0R, 0G, 255B.  In Photoshop, my color picker averaged it out to a spot Pantone 072 ( dark Blue ).  On press, the only way to get that color to print is to find some fringe florescent spot color, Bright Blue ( hypothetical ).  Check around and look at different spot color ink manufacturers like TOYO and Pantone florescents.
