I'm coding a website with:

background-color:#070707;

That color should be a very dark gray, just the way I see it in photoshop. Now when I launch this in my browser (the background-color is set on the body using CSS, so it's not an exported image), the color is darker than in Photoshop.

I know there can be differences when exporting images due to color profiling, but when setting the color code, how can this be different from photoshop?

Thanks a lot for helping
