color question

[Michelle Wilson]

Is there any place where you can put the number to a color in so you can use that specific one for a design? example I need to use this color number I was given: #d6b7b5 but I cannot find a place to put it.

And here is me feeling all proud that I winkled out the meaning of the question. [wry yet smug smiley face emoticon]

All true what said before. Those hex color numbers are used only with RGB / sRGB color profile.

No sane person would use them (without explicit mentioning) in other color formats.

That is not a colour number, it's just three hexadecimal values concatenated.

So what is a "color number"?

[Michelle Wilson]

My friend had business cards made. I am making a tumbler for her and she wants to use the font color from her card. So she gave me the number of the color that her person used. I’m new to design so I don’t know how else to reference it.

What you were provide is more commonly called a Hex Code, which apparently is different than a color number. Old Bruce provided a location in Affinity apps where that Hex Code can be entered.

The others were just being technical when stating the Hex code is not a color number.

I too am curious to what is a color number. I mean I don't want to fall into NotMyFault's category of being insane..

Hexadecimal Colour Code

or for the cool kids...

Hex Colour Code

Use either one and people will instantly know what you are referring to

 

Typically shortened to Hex Code or Hex Colour for experienced users or those that work in the industry

Thanks Ron. I didn’t know what to call it, but obviously someone knew what I was talking about because they told me where to look and I was able to do what I needed to do! 🤷🏻‍♀️I appreciate all the feedback! 

[Michelle Wilson]

Thank you for the information!

Now that I've said all that it will probably come out 100% the same

All this appears quite irritating and rather misleading than being useful for this topic. (to me it is not "pedantry" but confusion.)

@BofG, at least when writing "a human standard observer" I would expect you to wonder yourself about the theoretical approach of any objective, real, true, unambiguous judgement of a certain colour by a human. Not only it is the human only which develops, requires and fails in color reception and thus in definition, it is also a well known and often communicated issue where this chess board example is just one of many existing visualisations. – Compare the colour in the fields A and B … and then decide if LAB would make anything more clear than e.g. Hex Code to define the gray as numerical values.

 

Especially in DTP colour always depends on a complex system of various involved instruments, both hardware related (e.g. monitor, paper) and software related (e.g. calibration, profile), if print is involved it gets more complex simply because of the subtractive vs. additive property of colour. Thus colour is rather like language which requires a certain and known dictionary to be able to communicate specific information in an unambiguous way. Like words never have 1 unique meaning (e.g. "green", "tree", "hope") also colours depend on influences on the senders AND the receivers part (= screen / paper > eye). If more than 1 language is involved it gets even more complicated and may even appear impossible to achieve a "perfect" (true, correct, exact) translation. – Colour always requires a translation between at least two systems (~ "languages").

So it is no wonder and also an indicator for the ambiguity of colour that humans need so many differing systems and units. Colour can be described (> defined) as angle (degree), distance (wavelenghts, nanometer), temperatur (Kelvin), … electricity, reflectance, etc. (maybe volume or weight, too?)… and finally there is no 1 "true" system, measurement or unit but many.

Back to your mentioned "independency" as an advantage of LAB for the OP in this topic: It wouldn't solve the problem of required conversion from screen to paper, respectively the use of a certain profile. Below the LAB values are maintained if the document's space changes from RGB to CMYK ot graycale – but the colours …?

My statement might be irritating.

In the past 2 decades, the sRGB color model dominated the web (http browser, jpeg images, gif images, png images etc), and most color values were given in that context.

There was even the de-facto standard of https://en.wikipedia.org/wiki/Web_colors and Web-safe colors (inside that link)

There are numerous other color formats and profiles. Everyone is free to give a color code (normally just meaning the brightness value per channel). If no other context is given (explicitly mentioning color profile or whatever system is used to interpret the numeric values), it is quite common sense to assume sRGB.

Of course, in the print dominated world there is AdobeRGB, and CMYK colors. the issue with that is there is no common standard. You have numerous, so it is impossible to interpret color numbers without explicitly getting what CMYC color model is used.

 

The first answer to the OP question by bruce is all what the OP needs. The rest of this thread is actually deviating into academic irrelevance (for practical purposes).

Hex-RGB translation is a quite common question or task, accordingly there a quite a few tools online for such a calculation, for instance…

When "pedantry" was announced I expected more detailed, more precise information on the specific, initial problem of this thread. But your LAB excursion is simply any detail without any practical or theoretical benefit to the OP's question – not the promised pedantry. 🤓

Anyway, my whole point is that people think e.g. #99347C is a particular colour. It is not, it is values for the three channels. The colour produced is down to the profile used.

Well, which colour definition / appearance is NOT "down to the profile used"?
– The more misleading, useless part came later in your idea of "pedantry" by stating LAB color definition as "independent" …

Any of the CIE formats (e.g. L*a*b*, XYZ), those are device independent and instead relate to a human standard observer. Use those values and you are describing an actual colour.

… and thus ignoring that also a colour set in Affinity as LAB can change its look with a profile switch and thus for this "color question" topic LAB is neither more nor less independent than hex.

used in spectrophotometers and in the profile connection space precisely because they are profile independant.

There is no "objective" colour. Also spectrophotometers need calibration to work valid and reliable – and thus depend on profiles. Even a certain light colour (e.g. 6500 Kelvin) is based on a profile in a process of judging / measuring / defining colour.
Compare page 48 – 55: https://www.heidelberg.com/global/media/en/global_media/products___prinect/products___prinect_topics/pdf_1/color_quality.pdf

However, all your ideas in this thread about LAB, L*a*b* or CIE aren't "pedantry" but just an excursion to a quite different topic. Or, as @NotMyFault pointed out before, entirely irrelevant and of no practical use in this thread. It even appears you already have been well aware of this when you mentioned:

… just without mentioning: "Those weren't printed with LAB inks, too. " 

… More of this type of "pedantry" alias "water up the hill": Colour does not exist – it is only electromagnetic radio wave. Can't you hear it?

Only on my Colour Radio, the black and white one is monophonic.

SO HOW does one use the hexadecimal codes to pull up desired colors in Affinity Photo 2? Is there a tutorial...?

 

Thank You!

Are you asking about using the Info panel, the Color panel, or something else? Also, what do you mean by "pull up"? Are you looking for a way to apply a color specified in hex or something else?

[Cameraman1649]

I need to create a background of a specific color. I want to enter the hex code and be able to Fill the panel with the exact color.

Thank You!

In the Color panel, switch to RGB Hex like @Old Bruce suggested here, & then enter the hex code in the field next to the #: label.

Or double-click on a color well to bring up the Color Chooser window & enter it there.

MANY THANKS! I must leave now, but I'll try this as soon as I return.

But be aware that using a "hex code" may not give you what you want. The exact color it gives you will depend on what ICC profile you have specified for the document, and what ICC profile you specify when you Export the file.

[Cameraman1649]

I AM WAY BEHIND on this. Can you steer me to some valuable info on the workings of ICC?

Many Thanks!
