RGB and CMYK colors not matching up

Hey all,

 

Can anyone give any insight on why my CMYK color conversions don't match up to my brand RGB colors? To give an example, one RGB color I'm using is #074961, or 7, 73, 97. According to this colorbook, the corresponding CMYK color should be 35%, 9%, 0%, 62%. However, when I enter that in Indesign (I was trying to create RGB and CMYK color libraries across Adobe), it's a much duller color. When I convert the RGB swatch to CMYK in the swatch panel, it switches it to 95%, 65%, 42%, 27%.

 

Which CMYK value is right? Is CMYK different in Adobe v. elsewhere? If anyone else has encountered this issue, what CMYK value would you tell clients/put in a brand standards document?

 

(I was also told the Pantone value for this color was 4160C, but I can't even find that anywhere...so confused.)

Online color conversion charts are almost always wrong because there is no way of making color managed conversions via HTML coding. In the link you posted the sRGB/Hex values are correct because Hex is simply another way of notating RGB values and HTML defaults to sRGB. To make a CMYK conversion, you would have to use a color managed application and know the press profile—there is no universal CMYK profile.

The Pantone .acb libraies that are included with InDesign are out-of-date, and it doesn’t look like they will be updated. There is a new extension available for free from Pantone, that gives you access to all of the current libraries—4160C is included. Choose Window>Find Extensions on Exchange to add Pantone Connect to InDesign. This thread shows how to find and add swatches to your ID swatches panel:

That colorbook you refer to is waaaay off. I have no idea how they could have come up with that mix.

But let's ignore that for the moment. To answer your second question, there is no "RIGHT" cmyk value. Conversions depend on all of your colour settings and which profiles you are using in your workflow. Almost every situation is different, and you need to choose the right ones for your printing situation. If you want to establish a "standard" for cmyk, I suggest you use the only official Pantone cmyk mixes which are part of the Color Bridge color books. These will get you where you need to be 90% of the time.

As for PMS 4160, that's a new one to me, and it's definitely not in the Color Books the CC apps have right now, but it IS on the Pantone website. Their Color Bridge values for that is 97 31 11 59.
