I just started DIV and the nice colors of my perfectly calibrated Panasonic OLED TV are looking like the graphics haz fallen into a candy machine.
Anyone got the same problem? Or could it be that this is a “feature” of the new patch. 
I will start crying in 3… 2… 1. 
<— look what thou hast done!!!
hmm… perhaps its kind of art… “NEON DIV”? 
Yeah, some have, me including.
Clicking on the Adjust contrast and pushing a slider forth and back works.
Sadly, you have to do this evry time, you log into D4 at the moment.
I hope they fix the colors quickly. It looks like a child between dark graphics from DIV and Candy Crush
If i look at the red color of my 12/12 crossbow its like looking into the open fire of hell. My eyes are already tired.
I hope theres a special colorful place in hell for the person who did this 
Some folks had luck toggling their HDR settings
I wont change my TV settings only because they totally messed up the colors. Its unplayable like this. I cant read the items. My eyes are burning like hell (maybe thats the feature).
The characters colors are as usual but bars, item colors and text looks so awful extreme.
Is this how they want to look DIV now? Was it part of any visibility feature? Most important thing is… do they even know how bad it looks? Because theres zero information and communication from the devs side.
UPDATE:
Valuable Sir Franklin got the solution: turning “enhanced visuals” on and off and the colors are back to normal. But 50% of my eyes wobbely material haz already been burned 1000 Thanks dor the tip
