Bonjour, j'ai un petit problème sur photoshop,

 

Je vais essayer de vous expliquer ça au plus clair mais avec mes mots ^^

 

J'ai créer une banniere exemple pour un site, j'ai utiliser un code couleur précit, donc une fois l'image qui me plait, je l'enregistre sur mon ordinateur en jpeg. Quand j'ouvre cette même image, les couleurs sont devenu ternes, sombre pas jolie jolie :'(, mais quand j'utilise la pipette, elle m'affiche le même code couleur hmm donc la je ne comprend vraiment pas ce qu'il se passe. 

 

Si jamais je suis sur Mac, sur photoshop j'ai utiliserune résolution de 300 et le mode de couleur est automatiquement sur RVB , 8 bits/couche.

Different color spaces (sRGB, Adobe RGB, ProPhoto).

 

Same number = different color in different color spaces.

That post seems almost curt for you; it probably still qualifies as the »Correct Answer«, but didn’t you usually post more elaborate explanations to these kind of queries?

Yeah, I was in a hurry, still am... 😉

 

There's probably an untagged file here too,  sounds like ARGB or PP viewed without color management.

In that case I hope I did not unduly distract you.

Could you please post a screenshot taken at View > 100% with the pertinent Panels (Toolbar, Layers, Channels, Options Bar, …) visible? 

 

What is the image’s original Color Space?

Did you embed the profile when saving the jpg?

La question c'est avec quoi vous l'ouvrez ensuite? L'affichage d'une même couleur peut différer selon des paramètres liés au logiciel, à l'écran etc…

C'est la raison pour laquelle il est recommandé de bien régler dans le menu affichage :

Cocher couleurs de l'épreuve pour que Photoshop émule ce que donnera l'image à sa destination finale

choisir le mode d'épreuvage. Par exemple pour un affichage web SRVB (satanic/Stupid rvb)

De cette façon on traite son image en visionnant en temps réel ce qu'elle donnera au final.

Google translate gives me this: 

"I created an example banner for a site, I used a precise color code, so once the image I like,
I save it on my computer in jpeg. When I open this same image, the colors have become dull,
dark not pretty pretty :'(, but when I use the eyedropper, it shows me the same color code
hmm so I really don't understand what's going on happens. If ever I'm on Mac, on photoshop I use a resolution of 300 and the color mode is automatically RGB,
8 bits/channel."

Lets talk about reopning the image in Photoshop. [if you open in another application we need to know which one. AND it needs to be colour managed so it can read the embedded ICC document profile]

I'm betting this is a colourpace issue, as D.Fosse wrote different colourspaces produce
different visual appearances from the same RGB [or Hex] values.
If you embed the colour profile in the original document when saving, this will likely fix the issue

If you save as sRGB but with no embeded profile and open in Photoshop - with,
say, Adobe RGB (1998) set as default, then Adobe RGB (1998) will be used as document profile.
Hence the difference

I hope this helps
