How to change color of clothing to a specific HEX code?

I have an image where I need to change the color of the jacket from purple to a much lighter color: #eee7d9

...

So do I send it as this OR i start adjusting to visually make it look more like the purple in the color picker?

Hex is simply another way of writing RGB values and changes according to the color space. It was introduced in Photoshop when folks needed them to handcode html before the days of color management and is often misunderstood.

There are a number threads that address this — here is one. Read the replies from Adobe Community Experts @D Fosse and @davescm that explain it very well:

This method (for clothes, etc.) should in most cases come (much) closer or be more pleasing than a Hue/Sat layer. I don't have the mentioned action, but I think there is enough info in it to build it if you are action savvy.

Addionally, I would take out all color casts on the skin (or at least the ones from the clothing, if any).

Come to think of it, this might be a good job for AI.

The problem with that of course, is that you gain no further understanding of the basic underlying problem. The next time you're just as ignorant as you were to begin with.

And that, I think, is a precise description of the whole problem with AI. 

BTW, would this be considered to mundane a job for generative fill? Would it instead replace the jacket with a 17th century regalia army uniform? 😉 😄

I haven't installed the beta, so I can't try...

This is much more complicated than it sounds! For diagrams and pie charts this would work, for a photograph that is supposed to look natural there simply is no such thing. There's complex optics at play.

I'm not saying it can't be done, or that you can't get very close to how it would look in reality - but I am saying there's no one-button trick. This is a difficult job for an experienced operator!

The term "color" in Photoshop has a narrower meaning than it does in everyday speech: In Photoshop the color component is entirely separate from the luminance component. A numerical definition of a color will only apply to a flat patch of color.

So if you define a flat color, what about the highlights and shadows? They will obviously be a "different color" in the sense that the numbers will be very different. You can't just say "lighter" or "darker" either, because a given color will naturally decrease in saturation as you go towards white and black (both at 0 saturation). A garment will also pick up surrounding colors and reflected light, different in shadows and highlights. Neglecting this will make the result look fake and unnatural.

And then another thing: Every color has its own inherent brightness. This has to do with the eye's sensitivity to different wavelengths. A bright yellow is much lighter than a deep blue or purple! This isn't just a difference in brightness overall - it changes the whole contrast curve. So again - simply changing the color component will make the result look fake and unnatural.

Bottom line - you have to do this by eye. You will need to select the area and remap the whole tonal range with a gradient map. You have to pick an exact spot that you define as the reference for the new color.

In any case, the first thing you need to define is your ambition level: is quick-and-dirty good enough, or do you want it to look natural? If the latter, this is a lot of work and a pair of good experienced eyes.
