Color Question

Yeah but the hex value that is listed is for web.
Do you think the CMYK listed and the RGB and web-hex are all the same value?
AKA does the CMYK value = the RGB value?

For Web and Print? No of course not because they are different use cases.

The CYMK Hex value is 22408C the RGB value is 003893. RGB is for screen, CMYK is for print.

OK, so let's say I have the RGB value of (0,56,147) ... I want to convert that to a CMYK value to give to someone. How do I do that, and what would it be?

You're trying to convert a color for digital only to physical print so it won't be exact.

I know it won't be exactly eact, but it should be close.
So, what would that value be?
-
I already told you what the value is in CYMK Hex
22408C
-
But I don't want to go that way.
I am saying if I ONLY know the RGB color, and then want to get, say, a tshirt printed with that color, and the printer needs the CMYK value how do I find it out?

?? Dont want to go what way? You have an RGB, you want converted to CMYK, yes?
-
Yes. You keep giving me a hex value for a CMYK value.
I want to create a CMYK value from a RGB value.
So, if I got to this page, and enter in the RGB value, are you saying the CMYK value it gives me is not correct?
-
So you want to go from CMYK to RGB?
-
@DustinB3403 said in Color Question:

No, I want to go from RGB to CMYK.
-
And you want to go from RGB non HEX to CMYK hex correct?

Dustin - Willard's linked convertor disagrees with your hex value.
Edit - well, perhaps not - because while it says hex - it doesn't say if that's the RGB hex or the CYMK hex.
-
@Dashrender Shut up, you're getting this all mixed up.
The CMYK NON HEX of @BRRABill's example of C100 M89 Y10 K2 converted to RGB NON HEX is R0 G56 B147
Converted to HEX for CMYK that is 22408C and RGB HEX is 003893
-
If I use the CMYK to RGB converter, I do NOT get those values.
So, what am I doing wrong again?
-
@BRRABill said in Color Question:
C-100 M-89 Y-10 K-2
R-0 G-56 B-147
#000099Where did this information come from? As noted in the convertor @BRRABill linked to, RGB = 0, 56, 147 but that doesn't match any of the other listed data in Willard's first post.
So to me, that first post is totally broken to begin with.
-
@BRRABill Shitty software?
You could install GIMP and do this for free and be certain of the results.

Holy hell - those three options at the top are all completely different values when you convert them.
Hex from @BRRABill post
RGB - CMYK
CMYK - RGB
You'll notice all of the blues are nearly the same - but the are NOT the conversions from one set of numbers to another - they are some random post that @BRRABill found that some guy liked these specific values in each of those color options - NOT direct conversions.
So to answer you question @BRRABill
@BRRABill said in Color Question:
- I think the hex is wrong because I think HEX and RGB are always mirrors of each other. So the hex SHOULD be #003893.
Correct, it's wrong because it's something close, but not a direct conversion of the original line
- I have the CMYK coming out to be (100, 62, 0, 42). Again, I am assuming these three numbers should all be mirrors of each other, correct?
yep, again, these three numbers are NOT related - some random dude on some page you found just liked these three and called them close and made a post - but didn't use a convertor to do it.
So if anyone can shed some light on this colorful question, I would appreciate it!
I think there might finally be some light.

You guys have a serious omission in your conversions. RGB values depend on the color space. While we often use sRGB color space for the web, that's not often the case when the file comes from somewhere else.
CMYK is used in printing because that's the color used in a 4-color offset printing press: Cyan, Magenta, Yellow and Black.
Logos or other things that need exact color reproduction are often printed in 5 or more colors where the logo has it's own premixed color, not made up by CMYK colors. These exact premixed colors are Pantone colors and there are sets of pantone color swatches so everyone can see what every color looks like. Every company that has a logo from a graphic designer have the pantone numbers for their logo. That is the original colors so to speak.
There is not an exact conversion between RGB and CMYK unless you make a lot of assumptions and this varies between software and settings. Just as an example assume that you make a print using CMYK colors and one paper have a slightly yellowish tone while the other is ultra white. Will the logo look the same on both of these prints made with exactly the same CMYK colors? No, it wont.
When dealing with print shops it's often best to send the original file to them and let them handle the RGB to CMYK conversion. A TIFF file with embedded color profile is the standard here.
And if you are printing something that needs to be an exact color, like a logo, you should give them the Pantone number for that color. If you don't have it, it's probably not that important.
