Colorconverter from hex to CMYK

[DeePressland]

Hi! Is anyone here good with colours and converting to CMYK?

I'm trying to convert hex to CMYK, and I'm confused. I've tried three different sites and I get the same result on all three of them, but in Affinity I'm getting a totally different numbers. 

When I use the CMYK values from Affinity in one of the sites, I get another colour. I'm not sure if I can get the exact same colour to show on screen, but I don't want to mess up the colour codes for my client.

So which one should I trust?

That's a good discussion on Hex and CMYK that @thomaso recommended.

You can create an RGB document (I'd recommend using sRGB) and define your components using Hex codes (using the sliders). This will show you what your colors will look like an a typical sRGB monitor. Many colors will look different in CMYK, which is simply a fact of life we have to live with. The goal is to get as close as possible. 

If you need CMYK output, then, you will need to Export to CMYK and make sure you convert the colors to the proper CMYK document space. This will "dumb down" many of your bright RGB colors because CMYK inks simply cannot reproduce many vibrant RGB colors. The CMYK profile you choose can make a big difference, so ideally, your print provider or service should recommend an appropriate CMYK profile. 

To get an idea of how your colors will be impacted before Exporting, you can add a Soft Proof Adjustment Layer and set it to the proper CMYK profile. It's not 100% accurate, but ought to get you fairly close. Then, you can "tweak" your colors with the soft proof layer visible. Before Exporting to CMYK, be sure to hide the Soft Proof Adjustment layer. 

More information would help people guide you...Photo, Designer, Publisher? Printing to Press, an online digital provider, etc? What format do you need to supply? Is it critical to maintain vectors or is it okay to rasterize? A sample file would also be helpful.
