Help to export jpeg pictures !

Hi, 

I want to export a picture in jpeg file from photoshop, but once exported, the pictures looks lighter (less colourful). I have tried normal exportation with quality put at the max and exportation for website and many others setting. But it turns out always the same.

Please heeeelp, it is pictures for a clothing brand so very important for me the colour are good 🙂

Thank you
