Problème couleurs packshot produit

[Killian220679394bwr]

Bonjour, 
J'ai besoin d'avoir un fond sur mon image en #F4F4F4 (pour le web) Il est important que le fond reste avec ce code HEX exact. Hors lorsque j'exporte, cela change le code HEX et le fond devient du #F6F6F6. 
Avez-vous une idée ? 
Merci

How are you exporting it?

And I forgot to ask--what format are you exporting it to?

Hex is just base 16 notation for standard RGB numbers. RGB numbers are undefined until associated with a specific color space. By convention, hex usually refers to sRGB IEC61966-2.1 - but in practice, it is often used without any color management reference at all, and therefore uncertain. There is nothing absolute about hex numbers.

What is the color space you're working in? Not the working space, but the embedded document profile.

Aside from that, there is jpeg compression, which will often change the color values slightly - one or two numbers up or down. The jpeg algorithm compresses the color component much more aggressively than the luminance component.
